I don't know about Windows 95 (I've only owned Win 3.1, Win 98, and Macs),
but you can tell Windows 98's DPMI to be tougher about pointer dereferences
by telling it to protect memory. This will slow your program slightly, but
that's normal for debugging.

1. Right click your EXE. Choose Properties.
2. In the Memory panel, in the Conventional memory group, place a checkmark
next to Protected.
