Hi All,

I am trying to start three threads,

First Thread need to run constantly at least once in every 3 secs. Once Button1
Second Thread is supposed to play Sound on button click
Third Thread is supposed to vibrate the handset (Nokia E52) on button click.

now 2nd and 3rd thread must run at the same time so that user gets sound and vibration feedback at the same time.

Issue 1: Sound does not play at all. (Vibration works fine)
Issue 2: Application crashes on second button click event.

Please help i have been banging my head on this for a while now.

Kind Regards
Javed
