Anybody has mutiple sysNotifySleepRequestEvent?

[yinx...@gmail.com]

Hi everybody:
I'm using Treo 600, and trying to make some app. on it.Recently I
add I use sysNotifySleepRequestEvent to do my job, but I found the
result is always be odd.

I add "SndPlaySystemSound(SndSysBeepType(1));" to my event
handler, I found even if I only catch the sysNotifySleepRequestEvent
and do sysBeep in the corresponding handler, the beep will always beep
frequently after the Treo go to sleep ( the interval between two beep
seems has some relation to the idle timeout value, in my test, I set
the interval to 5 sec in convenience ).And the beep seems infinitly.
This means, as long as the Treo go to sleep and nobody or something
wake it up ,there will be always sysNotifySleepReqestEvent raise up
time to time.
Is this the fact?
