Hi,
If you're using this version of the script, there's a bug that can be
quite annoying. Symptoms: the OK button in any dialog doesn't speak,
and a lot of things aren't spoken. I was using the WindowDestroyed
event to detect that the preview was over. For some reason, this event
is never triggered for the Stop button, so the flag that caused the
speaking of the focus to be suppressed was never cleared. I think I
have a fix for this but will have to test it more-- and find time to put
it into a releasable version of the scripts.

Hi,
Attached is a test version of the JAWS Scripts for Audacity that
implements silencing of speech during preview.
The way I'm handling silencing the preview button seems a bit risky to
me. I have observed that when the Preview button is activated the
dialog is destroyed, focus moves to the Audacity main window, and a
dialog for handling the preview is created. In order to detect when
the Preview button is activated, I watch for the focus to move to the
main window. JAWS DialogActive() function returns false, so I can't
even restrict this test to a dialog. When I detect this condition I
set some flags that suppress speech during focus changes. I think the
next thing that happens is that focus moves to the Stop button. I
remember this window handle and terminate Preview processing when this
control is destroyed. This means that any time focus moves to the
Audacity main window, from anywhere, the Preview functionality is
activated. I haven't noticed any problems with this in my usage over
the past few months, but my usage patterns tend to be quite
repetitive. This is a tricky change, and I'm not quite sure I
understand my notes about it, or actually just what the state of my
development source is, which is a very good way to introduce major
problems into a project! I will release a test version when I figure
out just what files have changed, and how to adequately label the
version so we'll be able to recognize it easily if someone somehow
gets hold of it and reports a problem.
Oh well, attached are the files straight from my JAWS script folder.
If you'd like to test them, first back up your current script files.
Then save these files in your script folder and compile them with the
Script Manager. You might also back up
PersonalizedSettings\Audacity.jsi. I don't remember if the settings
file has changed or not, or if it would cause problems with the old
version if it did.
Here are the additions to What's new.txt since the 2.0 release. Notice
that the silence preview hasn't even made it into it yet.
(This file last updated 7/25/2014)
. The URL for the JAWS User's Guide can now be updated via the script
(Control+Shift+j).
. Added support for the QuickSettings dialog (JAWS 13 and later).
. Made messages for moving and selecting more consistent.
New in V2.0 (9/15/2013):

Thanks.
