Hi,
I've taken a look at Dorothy's problem, thanks to Léoni Watson for bringing
this to my attention.
The problem stems from the fact that the design of JAWS appears to treat all
white text on a black background as being text that has been selected by the
user. The NewTextEvent, which is responsible for reading any newly written
text to the screen, then reads all the newly written selected text in addition
to the current line. This will occur when you add text to an edit control,
scroll an edit control, or anything that changes the displayed text.
Eric Damery's suggestion of disabling the use of "Windows standard
highlighting" within JAWS will resolve this problem, although it will cause
problems elsewhere, such as not being able to read menus, and as such isn't a
valid suggestion. This should be curable by modifying various JAWS scripts to
change the logic in the NewTextEvent to realise that white text on a black
background doesn't always equate to the semantics of selected text. However,
this would be a required change in every script that implements the
NewTextEvent, and as such the easier fix would be for Freedom Scientific to do
a bug fix on their false assumption of white text on a black background always
equating to selected text.
If you upgraded to JAWS 6.10, I think it is, you may get some benefit from the
Enhanced Edit Mode feature that they introduced in that version. Although, I
have to point out that the Enhanced Edit Mode feature has it's own set of
problems.
