I am having problems with my newly reformatted work computer, XP and the DOS program we use.
Prior to installing XP a few days ago, we have been using win 98 SE and it worked pretty much fine with the DOS program we run.
Now, with XP, when I have the DOS program on (it's called Pentagon 2000, it's for the aerospace industry) everything else slows to a crawl. i pulled up the Task Manager and found something called ntvdm.exe using 99% of the CPU.
I need to be able to run both Pentagon and explorer at the same time.
Anything I can do about this?
