Hi Kamil,
I have confirmed that this technique works under both XP and Vista if
JAWS is configured to launch automatically when Windows starts. Is JAWS
running as a service in that case? I used to think that was the case,
though when I checked under Vista32, jfw.exe was listed as a process
rather than service in the Alt+Control+Delete task list dialog. If
there is something specific you'd like me to try, plese let me know.
HomerJax uses this technique, and I want it to be as broadly usable by
developers as possible.
