Unexpectedly Quit Problem,

I have an application (MPW C3.0) that allocates most of its
structures using non-relocatable pointers (NewPtr).  If the user
opens lots of windows so that there is not much memory left, and
then selects an option that loads a large code segment, my
application unexpectedly quits.

The only solution I have found is to leave enough memory for a 32kb
code segment to load.  I do this by checking MaxBlock each time I
allocate a new pointer.

Have others found this problem, and what is considered the proper
procedure to prevent it, or correct it.

Thanks in advance.
