We use two DOS applciations that ran with no problem under Win-98SE. However, when I attempt to operate those programs in "full screen" mode under Win-XP, the programs lock-up completely. They run perfectly in window mode, but the window is only approx. 1/4th the area of my screen and cannot be resized. I have activated full screen in the properties of the short cut to these programs and the full screen option under Display Options in the Defaults accessed through the title bar when the programs run in window mode and the full screen option under Display Options in the Properties accessed through the title bar when the programs run in window mode. Has anyone had similar problems and solved them? Any suggestions are appreciated!:disgust:
