Be sure you don't access the fields of the IntuiMessage after you've
replied it.  Are you doing any allocations inside of your event loop?

Also, FreeRemember(FALSE) is a very good way to frag the memory of
the system.

Try running with enforcer and memmung both active.

If all else fails, you may mail me your event loop.

ACTIVATE is not an IDCMP flag, it's a window flag.  Perhaps you want
ACTIVEWINDOW, which is the IDCMP flag to set if you wish to hear
when your window is made active.  This shouldn't be the cause of
your main problem, I think.
