RISC OS 4.39,
codenamed "Adjust" is distinct from the softload
"Select" scheme, as Adjust is only available on physical ROMs,
which are primarily suitable for RiscPC and A7000 machines.
Adjust contains all the work from RISC OS 4 up to and
including RISC OS Select 3, and adds a clutch of further bug fixes and a few
new features. RISC OS Select subscribers will of course receive all these
updates as a softload version shortly. The next full release of Select is
due later this year. The target audience for Adjust is those who didn't like, or couldn't use, the softloaded Select product (such as diskless machines).
For users considering upgrading to Adjust from RISC OS 3.x or 4.0x ROMs,
there is a truly staggering amount of new features to tempt - it's best go
to the RISC OS Select website to see details of Select 1, 2 and 3. For those
true RISC OS fanatics already running the latest Select 3i3 release, Adjust
still has all the improvements listed below to offer, and of course, reduced
boot-up times until Select 4 lands!
Below is a list of ROM changes between the latest Select 3i3 release and RISC OS
Adjust.Remember, that this is of course on top of all the improvements
featured in RISC OS Select itself!

manifested as incorrect Shift-Left/Right (skip word) behaviour.
Fixed TextArea left-margin selection redraw bug when using system font.
Now shows hourglass during TextArea file operations that take more than 1/3
second.
Implementation of double/triple/quadruple mouse SELECT clicks to select

selection to end of word/line/text.
The standard C library isspace() function is now used in place of custom
expressions when searching for start-of-word in a TextArea.
Extended auto-scroll of TextAreas during selection to correctly handle
horizontal as well as vertical movement in the case where word wrap is not
enabled.
Fixed the implementation of the TextArea_SetText method, which for some time
had been completely broken.
Fixed bugs in the TextArea_GetSelection and TextArea_GetText methods, which
were returning the string length in R5 rather than the number of bytes
written.
Fixed a bug where ADJUST mouse clicks could be used to create a selection in
a TextArea gadget that didn't have its AllowSelection flag set.
More low-level OS errors are now trapped and passed up to the client
application, rather than the relevant TextArea methods just 'going wrong'.
For example calling Gadget_MoveGadget may result in an error from
Font_Converttopoints (used during re-calculation of the TA margin width).
Fixed strange jerky scrolling movement when dragging the 'caret end' of a
TextArea selection on machines that do not support SWI Wimp_AutoScroll.
Rationalised faded rendering of the icons to use new Wimp interface.
Fix for font change on Text Area not affecting the scrollbars.
Fix for some redraw issues with sprite backgrounds on TextAreas.
Updated scroll bar plotting in ResEd for Scrolling Lists.

Multiple mouse clicks in a TextArea gadget will now cycle through the
different stages of selection ad-infinitum, rather than just flickering
subsequent to the fourth click.
Fixed a bug with the rendering of ScrollList and TextArea gadgets in ResEd.
More bugs fixed in the TextArea_GetSelection method, which behaved badly
when no selection existed and also consistently overran the stated length of
the client's buffer.
Fading a TextArea gadget now results in it giving up the input focus, which
is analogous to what happens when a writable field is faded.
The TextArea gadget now ignores attempts to alter the generic 'faded' flag
(bit 31) using the TextArea_SetState method; client applications should
instead use Gadget_SetFlags to fade or unfade a TextArea.
The TextArea_SetBackground method has also been extended to allow any
existing background sprite to be removed and to allow use of sprites from
the the Wimp pool.
A TextArea background sprite can now be specified by name as an alternative
to passing a sprite pointer.
TextArea_SetBackground now checks that the specified sprite is accessible
and (unless a Wimp sprite is being used) also verifies the sprite area. Any
subsequent failure to render the sprite will result in removal of the
background.
Bits 10-16 of the TextArea state have been reserved for various flags that
in future versions of TextGadgets will control the display attributes of any
background sprite (e.g. alignment and tiling).
Added a new method TextArea_GetWindowID to return the object Id of the
nested window used to implement a TextArea gadget.
Added click data to ScrollingList selection events.
Fix for Scrolling List selected colours when faded.
Unknown method numbers are now reported by the Scrollbar and TextArea
gadgets.
Detection of repeat mouse clicks has been tightened up to exclude the
possibility of false positives from rapid clicks in adjacent TextAreas.
Fixed a TextArea selection extension bug that manifested when the user
double or triple clicked ADJUST beyond the end of the final word on a
wrapped text line, and this caused the non-caret end of the selection to
move.
Fixed a bug in the tab-parsing code which caused wrong jump-to-next-word
behaviour when the caret position coincided with the start of a text line.
A TextArea gadget will now pass Ctrl-C, Ctrl-V and Ctrl-X keypresses on to
the client application when neither 'Clipboard' (bit 6) nor 'KeyNotify' (bit
8) state flags are set.
The correct component Id is now filled in for Wimp mouse click events on a
TextArea gadget; previously only the object Id was set to that of the parent
window.
Fixed a bug with using the TextArea_InsertText method to insert text
immediately after a newline.
