When it crashes, it should print a stack traceback and the registers' 
dump.  Does it?  If so, you should use the SYMIFY program to see where 
exactly did it crash and debug the reason for it.  Check out section 9.2 
of the DJGPP FAQ list (available as v2/faq202b.zip from the same place 
you get DJGPP) for details about SYMIFY.

When your program runs on Windows 95, it doesn't use CWSDPMI, because 
Windows has its own built-in DPMI server.  Your program's startup code 
sees this and doesn't load CWSDPMI.
