this happens alot, i have soldat oin fullscreen, and when i exit(since its stretched) my whole computer is stretched :(
i have to restart my computer when it happens, and it makes me not want to play soldat, any ideas?

don't play fullscreen

if U by streched mean the resolution is all soldat then try killing soldat (using CAD or if U have XP U can try cmd tasklist and then taskkill /PID <number from tasklist for soldat>

(has happend to me a few times lately)

If this happends, there's no need to restart, just change the screen properties. If it bugs you a lot just use windowed mode, like we normal players do :P

Your video card might suck. Make sure you have the proper drivers for your monitor and/or video card.
