I have an old Fox 2.6 DOS exe that a school wants to run. They have a new computer with XP Pro.

When program with the Full Screen oprion (which is what I want to do) it goes to full monitor screen (as desired), but the actual fox application screen reduces to about ½ the screen and the rest of the full window is just the background color in Fox DOS.

Basically it has crushed the application to only show on ½ screen.

If I run the DOS application in a Normal window (instead of Full Screen) then it looks fine but it is so small that I can not read the text.

How can I make a DOS program run in XP

I tried to set compatibility to Win 95, but that did not help.
