I'm only chiming in here with a way less informed view of everything going
on, so take what I say with x grains of salt, but it sounds upon cursory
reading suspiciously like horrible jaws video driver anomalies again, but
maybe somehow in particular relation to virtual stuff.
So the getting stuck issue is one thing to think about, definitely, and I'm
not belittling trying to solve that one, (have you tried invisible cursor to
do the FindColors?)
But, the fact that manually your getting a "black on black" response when
using jaws cursor to examine text, seems to me to pretty soundly point to a
substantial and more primary problem right there to attempt to solve first!
I've seen situations/versions of jaws where routing jaws cursor to virtual
PC, just fails miserably, machine bonks, (indicating some kind of awareness
of it's failure though,) and jaws cursor just ends up in either the bottom
status bar or top, etc.
and other situations where it kinda works, and puts one in the vicinity of
where virtual pc focus is, but not exactly. and then other sitches where it
has worked, and I've never been able to get to the real bottom of it exactly
ever!
I've also seen that issue before, quite a while ago now, which they did fix
in jaws, of the black on black being reported in IE, I think with jaws
cursor, but that was some time ago in jaws land now.
Rushing to get to a lesson but have you tried doing something reeeeally
crude like using AltShiftDownArrows in your script to force it out of that
situation, and then somehow doing a color search from that position down?
Although as I say, if your attributes are not even reliably being reported
manually when you get the jaws cursor on your text, that's the major issue
to resolve first I'd say.
Also have you messed with invisible cursor before activating FindColors? or
is it hardwired to use the jaws cursor always?
