Jason,
Even though you have matched all of your MemHandleLock calls with a
corresponding MemHandleUnlock call, your code may not be performing those
calls because of the program logic. I haven't seen your code, but that's my
guess. Check to make sure that you don't branch, or exit the form, without
executing the appropriate MemHandleUnlock.
Regards,
Steve

Yes, I miss typed, 10 times. I have gone over my code a billion (yes
1,000,000,000) times and every call to a MemHandleLock, has a
MemHandleUnlock. Every call to MemPtrLock has a MemPrtFree. Also the
program can run days, without any memory problems. I have narrowed it down
to a FrmOpenForm call though. So my guess now, is that something internal
to that function is not working properly.
On another note, Why does a call to DmResetRecordState cause a Bus error in
POSER and device?
Any ideas Palm Inc.?
Thanks,
Jason
PS: I have read Neil Rhodes Book cover to cover.
