Well, this code has been in there for eigth years now and gets called every
time, and it looks OK but might have problems when it runs out of memory.
Also, if your heap gets corrupted, a program gets unpredictable, which
explains why you can't find the porblem in debug mode.


First you should check if

p2wWPtr = (p2w_WindowPtr_t)NewPtr(sizeof(p2w_WindowRecord_t));

in p2w_NewWindow returns a valid pointer. Also make sure your heap is still
intact.


You can check if the heap is still intact if you type "hc" as soon as you
drop into MacsBug.

The error message says it all, just search all the other include files to
see where it is defined.

I think this group is just fine.
