I believe you have run into the problem where you are running FOXDOS on
a dual- (or more) processor computer. XP and FOXDOS and Dual-processors
end up running reeeeeeeeealy slow.
The fix is pretty simple, and involves replacing a file in the Windows
XP System32 folder....
NTVDM.EXE
with a modified version that has the processor affinity set differently
(I forget the techno babble details now.)
Windows File Protection will complain about it when you try to replace
the file and will attempt to restore the original file from the dll
cache folder, so you have to change it there also.
Shut down the System Restore Capability
Reboot the machine
Copy in the new NTVDM.EXE file
Delete the other copy in DLLCache and then re-enable the System Restore
Capability.
If you want I can either email you a modified NTVDM.EXE file, or you can
modify your own.

I have a customer running a program i wrote in 1990 in fox for dos with a
dos os, he has installed the program on a new machine running win xp.
the problem is now the program stops and waits for 5 minutes. I went over
today and ran the program interactively and found the program was stopping
at random spots. The thing I noticed was the speed of execution, it was
fast. I'm wondering if the machine is too fast. Any one have a suggestion on
how to slow the machine, or anything to suggest why the program pauses.
Thanks Jerry
