The problem is that you actually have less memory available when you
run XM since it is a larger monitor. And we're talking about memory
in the critical area of the low 56kb.

What you need to do is try running the program under XM, but using
the 'virtual background executive' program, VBGEXE. This will
move the program into extended memory, but the program will see
much more available memory in its virtual address space.
