I have this program called McRazor which turns the Palm into a razor. You
can find the current copy at http://members.xoom.com/mjmdlm/palm/. I am in
the process or using the non-blocking sound. When a for pops up and causes a
beep or a click then my sound stops. Well, I want to "turn off" my razor
when and before another form pops up.
Thanks,
Mike McCollister
