Hi all,

Has anyone experienced problems with GO32 running in a DOS session under
Desqview/X?

I have been attempting to get to the source of this one for 2 weeks now and
have traced the problem down to an interaction with all 3 programs (PC-NFS,
DVX & GO32).

If I have PC-NFS running, but not DVX and try to compile a program using
DJGPP everything is fine :-)
If I have DVX running, but not PC-NFS and try to compile a program in a DOS
session (with 500K of real memory) everything works fine :-)
If I have PC-NFS running and DVX (v2.0) and try to compile using DJGPP in a
DOS session the machine hangs :-(

After much investigation I have found that I always get an "Invalid instruction"
exception at the same address in the PC-NFS driver. I have tried moving the
driver to low memory, excluding many areas of the high memory using QEMM and
removing all unnecessary TSR's. I have tried all combinations of TSR's and
driver's, I have tried running thru the EX13FLOW technote from Quarterdeck, I
have tried everything I can think of now and have not had any success :-()

If anyone has any suggestions please let me know.

The versions of the software I am running are as follows:
PC-NFS		v5.0b
DVX		v2.0
QEMM		v7.04
DJGPP		v1.11m5
DOS		v5.0
