MemoryMgrNew Crash

[Stuart Norton]

Hi,

I'm fairly new to all this, and am getting a crash on hitting the 'Apps'
button (just an appStopEvent on the queue) which looks like this:

Fatal Error:
MemoryMgrNew.c
Line:3970, Invalid handle

It then fails to reset from the button in the box.

Can anyone tell me what's likely to be causing this. (I'm using MemPtrNew
commands, but with MemPtrFree at the ends of the functions where they are
used - relevant?).
