I work all the time with QEMM and QDPMI and never saw such problems.  What 
programs crash under QDPMI?  Are those the programs which are distributed 
with DJGPP (the compiler and development tools) or programs you write?  
If those are your programs, are they graphics programs (graphics doesn't 
work in DPMI mode in DJGPP 1.x)?  What happens if you leave QDPMI ON, but 
put this into your GO32 environment variable:

	set GO32=nodpmi

(If your GO32 is set to something, just add `nodpmi' to whatever it says 
now.)

If nothing of the above supplies the answer, tell us what does go32 print 
when called with no arguments (with QDPMI turned ON) and give some 
details about your hardware and software set-up.
