I am currently running windows 7 ultimate on my laptop. Windows 7 cannot run dos based applications like C++ 3.0 in full screen mode. therefore i use dosbox for running it in fullscreen. But when i mount the C: and run C++, the screen turns red... when i minimizes it, it again becomes normal. When i again maximizes it, the problem arises again. This is so annoying. I tried updating my version of dosbox from 0.72 to 0.73, but its of no use. plz help me...
