I am working on a DOS console program in Borland C++ and for some reason, the entire screen flashes when I have it running in full screen, but if it is running in a window it is perfectly fine. I am only cout'ing 2 characters with each pass of the loop (erasing one with a space, and placing another). Does anyone know what I should look for? I am completely stumped on what to look for first. I can't find a logical explanation for the entire screen flashing, not just characters, but the entire screen going black for a half-second and then coming back. I know it isn't my computer or monitor because my other programs work fine and it does the same on a friend's computer.
