Significant reduction in number of times reformatter is called during
a table widthing session results in a dramatic speed increase for nested
tables (e.g. 64 deep with a paragraph of text in the deepest table takes
about two seconds to load with near-instantaneous subsequent reformats,
as opposed to taking optimistically 28 days for a 32 deep table!).
This code relies on a very big stack of assumptions...

Save as plain text implemented.

Choices, Messages and Res files brought up to date where necessary.
Version number taken to 1.28, 04-Dec-97 (so I don't forget later,
basically...).

Forgot to add in ImgHistory.c / h last time. Note also that only the Browse and Ursula resources are up to date at this point - bits are missing from the other builds.

Image history - sizes of images are remembered for future reference (if the sizes aren't specified in the HTML, they can be looked for in the image history instead to minimise reformatting requirements). Choices file options ImageHistoryPath, ImageExpiryAge, ImageMaxSize and

SaveImageHistory added to support this (all have a direct analogy to
the global History items of the same name after removing 'Image').

Text area items are now the correct height for the number of rows
specified in the HTML, don't scroll a line too early, and have the
caret placed at the start of the text when moved into from above
or at the end when moved into from below (rather than always at
the end, which was behaviour inherited from single line writables,
where this is desirable). The top of the text area is aligned to
the top of any line of text on the same line, with the text area
dropping below the text, rather than the bottom of the area matching
the text baseline and extending upwards.

Filename extensions for download files are only stripped if an
attempt to convert to a RISC OS filetype through the Mime Mapper module
does not return an error or Data (0xffd) filetype. '.cgi' is a special
case which is always stripped.

Altered heading styles - all are bold, none are italic, H3 is as big
as H2 was, H2 is a little larger, and others scale down to H6 being
the size as normal text (but, as I say, bold).

Sorted out tables and forms. We can just look for tagno=TAG_FORM, and
get rid of the wobbly form_flag; also discarded the redundant
reprocess_table flag in fetch_preprocess_token. Two separate forms
in consecutive table cells (for example) which used to fail - they
were submitted as one single form - will now work correctly.

Fixed nasty bug in FontManage.c where font size 7 would intermittently
fail. The stupid font sizes that it could ask the Font Manager for may
be responsible for the occasional Font Manager crashes that have been
noticed. Array for font sizes was declared as [Limits_FontSizes], but
indices 1 to Limits_FontSizes are actually used - so needed a '+ 1'
in the declaration... :-/

Replaced the case insensitive string comparison functions in Utils.c
with more efficient versions by S.Brodie.

MAXLENGTH specifier in INPUT tags is now supported. If unspecified or
specifically zero, the browser overrides and allows any length.

Adjust-click on forwards/backwards buttons did not work in the intermediate
build, and now does.

Adjust-click on form submission buttons where the submit method is POST
will now work correctly, as the new view inherits the extradata block
of the old. Failure of this is signalled through
make_no_fetch_memory_error, code 16 (see updated Errors file in Docs).
Note the name change of extradata in this context; more details below.

The passing of forms POST data and extra headers for sending in an
HTTP request via. the URL module was all done through pointers into
flex blocks, and was therefore very unsafe. All relevant functions now
use pointers to pointers to the data.

To remove confusion on the umpteen uses of the word 'extradata', the field
in browser_data has been renamed to 'post_data'. The 'extradata' parameters
used within FetchPage.c were all disconnected from the extra header info /
form POST data stuff that extradata is usually associated with, and have
thus also been renamed, in this case to 'appnddata' (Append Data).

As well as X-NoProxy, the browser sends the 'proper' HTTP headers
Pragma:no-cache and Cache-Control:no-cache.

A redirection from a POST request was not handled correctly; despite
what HTTP specs say, you're supposed to use GET for the new URL. The
browser was, but when it chopped off the redundant header data in the
request didn't terminate it and left Content-Type in anyway...! Fixed.

Ctrl+Tab implemented - URL completion. Comes from the hotlist URLs,
hotlist titles, history hosts, paths, full URLs and lastly titles.
See code comments for more (history_find_match, hotlist_find_match).

TableSupport option added to Choices; it is read, can be set by the
front-end, but doesn't actually do anything else yet.

Reversed Choices' semantics on 'don't expire by...' for History. Added
'needs_redraw' flag to choices_get_contents so that, for example, if the
table border types change, browsers get redrawn.

This is an intermediate check-in to allow work on Choices for the new table options and History choices as detailed below. Res files are not up to date except where indicated and there are several known bugs that will be fixed before the 'final' v1.27 is created. Any work on resources should only be done for the testbed !Browse.

Client side image maps implemented. There is code to draw highlighted
borders in CSIM.c, but this is not wired in yet; other than that,
the implementation is functionally complete. As part of this, centralised
the fetching of a targetted URL taking into account user request of a
new view and full screen mode, in fetchpage_fetch_targetted. The forms
library now uses this too, so form buttons respond to both adjust-clicks
and TARGET attributes.

Fixed APPLET handling where '.class' isn't present in the CODE attribute.

Paragraphs squashed at the top of cells/pages - browser would insert white
space before.

Now append a ' ' to the end of History menu items to prevent the Wimp
thinking the end of entries represents a keyboard shortcut (e.g. 'Home').

Netscape's handling of 'meta http-equiv="refresh"' is to start counting
when the fetch has completed and everything else has died down. The browser
will now not start counting until the animation handler is deregistered
(so formatting is complete) to show similar behaviour (note that this
checks the main handler, not the 'idle but returning to first frame'
drift handler).

URLs from requests for fetches by Plug-Ins are now relativised.

Page width change tolerance prior to reformat upped from 16 to 32 OS
units. Hoping to provoke a loosely connected bug with this change!

TableOuter, TableInner and SeeFetches choices added to all Choices
files, with appropriate loading and saving code in Main.c and Save.c.
AuthorFTP and AuthorFSh messages added for FTP authentication, and
dialogue handling code (the component in FetchHTML.c) updated to
recognise an FTP fetch and alter the dialogue presentation
appropriately.

All Messages file version numbers taken up to 1.27 (20 Nov 1997).

Following a UseNet suggestion, Ctrl+Toggle Size will increase the window
size to fill the screen vertically only; horizontal size/positioning is
not changed.

Shift+Tab in the URL writable will cycle through alternative fetcher
protocols (from both the Controls file and checking the fetcher modules
are actually present).

Hotlist doesn't require '://' in URLs when loading HTML, just ':/' - so
'file:/' URLs now will be reloaded correctly.

History system rewritten completely. GHistSize and VHistSize options
removed, and replaced by MaxSize and ExpiryAge. Now have global history
menus with most recently visited items at the top, and local history
menus which reflect the path that forward/back buttons would take.
Browsers are robust to background expiry of the History though this is
not implemented - date expiry and size checks are carried out on
history_record only. This does mean that with two windows open one could
have the history expired underneath it whilst another fetched, though;
the code handles this and update toolbars (greying items) as necessary.
It is possible to have the history limits so tight that even one entry
will not fit and again the code copes with this, though values read
from Choices are limit checked to ensure rather more useful results!

Implemented 'Save' button in save dialogues. Remembers pathnames and just
replaces the leaf now (hard coded exceptions for <Wimp$Scrap>... and
<Wimp$ScrapDir>...) - it did before, but only if you'd typed the path
in. Not many people did, given that you couldn't press Return or click on
a Save button to use that path...

In a similar vein, files of type Data or DOS will be checked for a '/xxx'
type extension and the MimeMap module will be used to find a more meaningful
filetype. If this can be handled, the file is loaded. This only works for
files dragged to the browser - the behaviour with inline data in web pages
will depend on the File module, and similarly, if File doesn't spot what is
going on and claims that the object is data, the browser will just open a
save dialogue for it.

!RunD files taken up to 3072K WimpSlot.

Hotlist's saved HTML page title wasn't internationalised - is now. This
opened up a significant can of worms; on file write error, the file would
never be closed, and if a caller of the save or load functions passed
in a filename held in the global Messages lookup buffer then subsequent
lookups in the callees would corrupt that filename. All sorted out now.

Local (not very useful) or global (useful) histories can be saved as HTML,
which opens up the possibility of sending your history to the hotlist
by saving to it. Local and global histories can also be emptied, though
this is probably not a feature that current release Desktop browsers need.
Inheritance of local history and certain UI features is now done more or
less for all cases where one browser window spawns another, too.

Vertical alignment on images is rather less ropey than it was (e.g.
ALIGN=TOP stands half a chance of working) but is still far from perfect.
This was part of fixing a nasty little bug in Redraw.c's setting of
an image position via. image_set_token_image_position, which was making
(amongst possibly many other things) client side image maps fail.
Image update where images had large borders was affected by a similar
problem too (more cans with more worms...).

Fixed image background filler functions; two problems. When cross
referenced images were replaced by base images in a browser because the
original owner was closing down, the original owner browser would stay
registered with ImageLib. Fixed; secondly, when images were deleted from
the image array causing those above to be renumbered, images registered
with ImageLib did not have their numbers updated (this was the one that
lead to the visible drop out of background images with PNGs on the Acorn
Internet home page when there were two views of the page and the first
was closed). This is now also sorted out.

Stopped UNIFONT forcing system font use and added calls to Font_WideFormat.
Made sure the system font option is read before fm_init is called!

User agent string now set if Netscape faking is disabled (format used is
"Acorn Browse/1.26 (RISC OS 3.71)".

Removed 'The Onion' link from some Hotlist files. Time showed that the site wasn't entirely Family Friendly (TM)... Removed Shift Control (it's gone offline now), and corrected the Telegraph URL from ...the-telegraph...

to just ...telegraph...

StrongHelp manual generator now tries to work out the number of lines in
the table on the root page more intelligently.

Plug-in support extended to handle Shockwave. Quite a lot of underlying
work for this, including a pseudo cache system for temporary files.

Bug in redraw routines: they plotted background images within table
cells, when nothing should have been drawn. Oops. When background images
in cells are properly supported, this can get sorted out.

Tweaked vertical plot position of HRs (up to 4 OS units too high before due
to rounding).

Various Res file bits and pieces, Ursula build taken up to v1.26 beta
for release on the Browser site. *Note* not all resources are up to date!
This will be done after AW97.

Res files sorted out a bit, to add the Proxy option to the Choices dialogues
and fix the position of the menu popup in the Others pane.

Bogus comment in Global.h showed up when trying to build the Customer
variant (SINGLE_USER undefined); fixed.

Various fixes in the code required for Shockwave support (many invalid assumptions about the OBJECT tag structure). Not finished yet though.

Played around with signal handling 'n' all that to try and get sensible
errors reported for aborts etc. using code by KBracey. Need a ROM patch
for _swix on RISC OS 3.7 upwards (or a local fixed copy of _swix),
otherwise should sort out most of the problems seen (mostly 'no stack
for trap handler' errors and a distinct lack of a register dump).

Plug-In view on redraw / ASAP choices now work as they should (ASAP
was previously broken).

Version numbers in Messages incremented to 1.25 (23 Oct 1997).

For Plug-In support, created new source file RMA.c/h to handle RMA
claims and releases, in an attempt to ensure leakage never happens.
As such, this source is *slightly* more advanced than that in the 1.25
AW '97 build, though functionally identical. Well, that is, at least
you can confirm zero RMA leakage with '-debug LMem' in TRACE builds now!

Intend to do a consistenc...

fetch_get_raw_data will notice if up->fetching is zero and return a 'finished' status rather than trying to continue reading data for the fetch. Fetches should never fall through that far but at least it will cope if they do.

3D table borders are now supported. 2D borders are used if the
inter-cell spacing is too small to fit the borders in (display resolution
dependent) - the external table border is 2D if the internal borders are,
else 3D. For cellspacing of 0, internal table borders must plot over the
outer edge of pixels inside the cell; for all greater spacings, the
borders take up all or part of the gap between them. The external border
will always fit around the outside of the cells, including the
cellspacing value in the gap between the outer cells and the border.

Anti-alias colour for placeholder ALT text was incorrect. Fixed.

I'd changed 'point' to 'points' in some of the Font Choices dialogues;
now changed back to 'point'.

The routine to find out how large an otherwise unsized object or imag...

Sorted out Res files, including fixing position of 'bytes' label in one of the Choices dialogues (I'd missed it out of a selection when everything else got moved down a bit). Unfaded Enc_Chinese menu entries, made sure text labels were wide enough for system font, changed 'Apply' on Choices dialogue to 'Set', and added ^K to hotlist keyboard shortcut lists.

Print Setup (i.e. Print dialogue) buttons all set to 'local', so the
stupid Toolbox doesn't close the dialogue and lose the caret before I
can see if it was in there to start with...

256 colour hotlist sprites taken back to standard 16 colour versions,
since there's a significant speed penalty on slower machines. The
testbed browser still has the 256 colour versions so the designs aren't
completely lost.

Changed access settings to exported builds to wr/r - lr/r was really getting
on my nerves whenever I wanted to try something temporary out.

View source, save source and print handlers would all try to work if
there was no source to act on - despite the fact that toolbar buttons
would be greyed out form them. This is fixed.

The Navigate menu has components greyed to match the toolbar state,
when opened. It isn't kept up to date dynamically, though this shouldn't
really be a problem (reopen the submenu...). As part of this, finally
sorted out conditions for the Stop button to be greyed, or the
GoTo/Go/Stop tristate to be at 'Stop' versus 'GoTo'.

Deferred reformatting is now disabled for external image fetches.

Browser-local client pull flag removed; hitting the Stop button simply
cancels any null handlers working for it. That way, client pull switches
back on in passing at the next fetch (it was never really switched off).
So to stop client pull, hit the stop button at any point.

Done CELLPADDING attribute; cellpadding field in reformat_cell (Global.h)
is redundant since the table token is accessible from there, and so it has
been removed. CELLSPACING support also added.

Now handles PARAM tags. Sorted out Plug-In bug that was related to Java setting a 0 by 0 graphics window before calling Wimp_Poll (fixed in Java).

Implemented queue for Plug-Ins so multiple broadcasts aren't sent for
several Objects in one data chunk.

Added Docs directory with some documentation in it. More things to keep
checking for stylistic consistency, horray ;-)

Corrected !Run[D] for Ursula build to need AcornURI but not TaskModule
(URI handler needed for !Mail to pick up mailto: links).

Added display_height field to browser_data, analogous to display_width,
to cope with % sized objects by width and height (see how HRs are
handled in Redraw.c for an example of how it was always fairly easy
with width, but not height until this addition). Though you do have
to reload to get a new size; reformat isn't enough. Must see to this
some time...

Fixed bug where basic typefaces were claimed *before* the Choices file
had been read. For unusual Choices settings, this could create some
'interesting' problems now and again. This was part of narrower scope
work in the Choices code to allow font changing without leaking font
handles (now done; fm_shutdown only ditches fonts, it keeps internal
structures - must then call  fm_lose_fonts for all browsers to get the
bitfields up to date, then rewrite the typeface definitions and reclaim
basic fonts). Noticed that fm_claim_basic_typefaces would claim multiple
instances of the same font if there were several cases of the same font
mapped to different typeface styles - fixed.

Implemented PlugInControl settings, but not SupportObject (fully).

Minimal support for font choices added, fixed problem with colour changing with browsers with no background colour specified.  Options for Objects implemented.

So I added it again.

More reformatter code bugs fixed; this one regarding width of items. Any kerned string was overestimated (causing redraw bugs and caret position problems in forms, apart from other minor bits elsewhere) and the default size of a writable icon wasn't especially clever.

Crude Plug-In support; just about manages Java, but can't fetch on
behalf of Plug-In (for example). Had to change the default file access
URL construction to be 'file:/' instead of 'file://', or local file
fetches that reference Java applets won't work. This is in its very
early stages, and is being checked in mostly so that various Choices
issues can be worked on.

!Run[D] files updated for new fetchers and GopherFetcher; protocols list in Controls updated for Gopher. Debug builds now require 2760K rather than 2560K. Font$... variables set if not already, in anticipation of font

Choices work.

Additional bits in Choices section of Res file tidied and some name
changes (e.g. Netscape -> Navigator(TM)). Frames support option added
to Choices.

Grouped 'support_frames' under the Fetch Controls section and added
support_object in Global.h; appropriate entries placed in the Choices
files, and are read at startup. At present, though, only the frames
support flag is implemented.

For some reason, Menu was the button to use on history popups if you
wanted to show URLs instead of descriptions (or vice versa, depending
on Choices settings). Now, Select and Menu will show the Choices
defined setting, and Adjust will show the opposite.

History menus are built backwards, so local histories have the most
recently visited pages at the top. Global history has still no real
order t...

FRAMES_SUPPORT #define removed.

Optimised fm_token_font_info().

Added support for LI tokens with text (for ordered lists).

Now outdents bullets from indent value, rather than indenting bullets by
the indent value and further indenting text. May need to look at default
Choices files because of this.

Limited the margin to always be non-negative.

Added MimeMap module support. OBJECT routines now use this to determine if the item is an inline image, and if so pass it to the image routines.

At present, support relies on a (correct) content type.

Choices now allows gadgets to be in any subwindow with some limitations which are addressed in the header file.  Also there is no longer a concept of named subwindows.

Res files had component 0x29fc in frame gadgets for Choices - that's meant to be the 'fake page' display. Sorted that out.

Got rid of unnecessary #define in Choices.h; the gadget autodetect
for the colour choices took its place.

Unsized objects now default to the same dimensions as unsized images.

Calling HtmlEndParse at the end of html_get_next_token and setting up->context to NULL was wrong; fetch_fetcher would end up recalling html_get_next_token later which would then call HtmlParse even though the document parse had just finished! The HtmlEndParse call has now been moved to fetch_stop.

Altered reformatter to claim fonts inside a browser, rather than
claiming them for nothing and losing them afterwards.

Got rid of TAG == TABLE and ISBODY tests, replacing with tagno == TAG_TABLE.
Removed all references to TD, TH, TR and TABLE in the style word.

Big steps forward in vertical white space handling as a result of improvements in HTMLLib in this area ( -> all versions now 1.22 beta-2).

As a result, the 'last_space' field in browser_data struct has been
removed. Note that this relies quite heavily on setting of the PCDATA
bit in the 'style' field of an HStream and the automatic collapsing
of (for example) multiple P tags inside HTMLLib.

Trace.c improved to recognise various bits in the 'style' field of an
HStream structure.

Phoenix defaults altered to a more 'standard' set of choices; Trinity
as the serif font, with a slightly larger default font size. This is
because there's a good chance it might get released to a wider audience
than Acorn internal (though the animation and icon bar sprites will
have to change before then...).

MiscDefs updated for new SWI numbers in HTTP module; !Run[D] files thus
updated to require HTTP 0.42 or later. At this point, all earlier
modules are not backwards compatible in terms of direct calls to the
HTTP module, though this only affects cookies_process_cookie at present.
At the same time, checks for System$Path, InetDBase$Path, and setting
of Inet$MimeMappings if not already defined have been added to the Run
files along with RMEnsures of Resolver and MimeMap.

Object and PlugIn c/h pairs created to handle OBJECT, EMBED and APPLET,
and the RISC OS Plug-In interface respectively. Not part of the build
process yet. Addition of 'odata' field in browser_data struct and
definition of chunk CK_OBJB for memory_set_chunk_size() are in support
of this.

Updated Res files in appropriate builds to hold various (similar) Choices
designs.

Choices related menus were flagged as Shared, but none of the dialogues
(including ColourDBox) were - potential future problems, though shouldn't
cause any leaks at present. This has been sorted out anyway.

Encoding function encoding_init no longer returns an error from
toolbox_create_object, so the Encoding menu and all those attached
to it do not have to be present (e.g. the Customer build).

SUB, SUP, STRIKE and U supported. U underlines the baseline of the body text
font, whilst STRIKE will go through roughly the middle of the lower case
chars even if the font is SUP or SUB. Note that Navigator appears to shift
the underline point for SUB and SUP; it may be necessary to copy this
behaviour, but testing on real sites must proceed before that. There could
also be a problem with the automatic lowering of font size, which Navigator
doesn't do, so any FONT SIZE = -n commands coul...

Changed some error handling in Choices, a little bit of reformatting, removed unnecessary tempstring in Main, and played about with the choices Res file objects.

Text items with no VALUE specified in the HTML were not cleared on
hitting a Reset button as the text field of the token is NULL; fixed.
SELECT lists with no default selection item were not being changed
on hitting a Reset button; fixed. In radio groups with no default
selection specified, no item will be selected. This goes against
the HTML 2 spec but allows broken Navigator-esque forms behaviour.
In consequence, radios can be deselected by clicking on the same
one twice. I'd fixed the flickering experienced when doing this
recently, but that, now, is irrelevant, since the state of a radio
must always change.

Reformatter's new 'find width of a SELECT field' didn't account for
the width of <none> and <many> items, and now does (particularly
important for broken items with no OPTION contents).

Under certain circumstances, illegally named targets would open in the
ancestor rather than a new window - a deliberate decision in the code,
but now reversed due to a test suite failure; they'll open in a new
window instead.

Altered the left hand indent handling for lists so that headings and
body text follow the Navigator 48 pixel indent and the bullet point
items drop to the left of the left hand margin, rather than sitting
on the margin with the text indented to the right.

Tightened up the hotlist_load_directory checking of URLs, so that
only those with '://' in - i.e. look fully specified - are accepted.
HTML files are loaded into a new directory now.

Items without a descriptive title in hotlist_new_url will have the URL
substituted in instead. White space before and after descriptions and
after URLs is stripped. Directories with zero length names or null
strings (after white space is stripped) will still be created, with a
generic name (see Messages, token 'HotlistUntitled').

StrongHelp generator on it. Revealed a spurious toolbox_hide_object call
that would always fault and never do anything, and a few heinous uses
of show_error which have all been removed.

When dragging hotlist items, directories will now be highlighted whenever
the item would be added to them, rather than just over the sprite. In
practice this only changes if the item is open and has contents...

Drag box selections had broken in the hotlist; fixed (uninitialised
variable in hotlist_select_box). Adjust-drags now close the window on
completion. Minor problem with Shift+Drag (copy) reversing order of items
sorted out. Added hotlist_add_html_file and implemented loading of HTML.
DO NOT add broken HTML files, this has not been coded for and URLs of the
form http:///this/that (no host name) will hang the machine (bug in the
cookie code of the HTTP module up to at least version 0.39).

Made SELECT list items only as wide as the widest entry...

New save choices function with supporting code in Save.c; 'Save choices'
option in the Choices menu is now implemented.

Choices and Controls files are now loaded into malloc space (use chf and cof to address them). Previously only in Main.c, task_dir is now globally visible.

Choices updated to allow 16ths of a point in the font size specification
and the System font face has been removed - it isn't used. The use of
serif and sans serif fonts has been rationalised across builds (e.g. Desktop
builds use what they say, but the Customer build uses Homerton as the
default body (serif, so to speak) font as it matches the box's look and
feel better).

Font loading altered a bit to work properly! Font library defines some
standard startup fonts without using Choices, which Choices can then
override.

Now working on source merged with Kevin Bracey's internationalisation support. UNIFONT is undefined in the Make File for now. All Res and

Choices files updated appropriately.

Having sorted out the old Choices and Messages to form Choices, Controls
and Messages, this build has had the same cleaning up done internally.
This includes greater consistency in naming schemes and the removal of
the inconsitent choices items - e.g. Choices file entries saying 'delay
images' and 'plain backgrounds' where internally all the flags say 'show
images' and 'show backgrounds'. ChoiceDefs.h and CtrlDefs.h added to
clarify the meaning of some fields, though usage of these is not 100%
in the source (there are cases where parameters are passed through to
functions as ints, and those functions still check these against hard
coded values rather than the #define stuff).

Fetcher status return bits (connected, sent request, etc.) now reflected
in status bar. Progress during fetchs to files are reported by %, where
the size of th...

Encoding support added: if UNIFONT is defined then the browser will attempt to use the system font to render Unicode characters (new

International module required). If not defined, the browser will just
handle Acorn Latin-1 characters, but HTMLLib will convert other encodings
into Latin-1. Must keep the UNIFONT define in sync with HTMLLib (if
defined HTMLLib outputs UTF-8, otherwise Acorn Latin-1).

Still needed:

Reverse encoding (converting form input etc back into the server's
character set).
Reparse when encoding changes.
Setting of charset from an attribute on the <A> tag.

Image deletion routines rewritten; nasty animated GIF bug now gone
(it kept trying to update the cross-referenced image in the browser that
no longer existed, and I've no idea how animated GIFs ever managed to *not*
blow up if a cross referencing browser was shut down; and I've tested
this...). There are now as many image structures as there are total images
in the visible browsers, and no more; cross referenced images in the
to-be-deleted browser have their ownership moved to the cross
referencer before the cross referencee is wiped, with any required fetches
being transferred with them.

Reformatter sped up a bit by getting rid of strlen on the main text field
of tokens in all places bar one, where it is called extremely rarely. This
means direct app-to-app transfer of, say, a 359K text file to the browser
won't run like a drain as it tries to do strlen on a 359K string over and
over again! Most of the time the performance benefits won't really be
noticable, ...

Added 'save current location'. Res files updated appropriately. Version number taken to Beta-3; next will be 1.21, including K.Bracey's i18n code.
