I am in no way a computer expert. I hope someone here can help me. I use a Dos program at work for estimation. It runs in dos and not windows (well always has till now)It now comes up in windows and it is about a 1/4 size of a window(in dos it was always the size of the screen) Why would it all of a sudden start up in windows and not dos? And I can not get it to maximize. I have gone to property and click on Maximize and it will go to maximize for about 5 seconds then shrinks back up. I just can not get it to stay large.Anyone know anything about Dos and windows that might know the cause? I have used this for about 15 years and never had a problem till about 2 months ago. HELP!!!!!!!!!
