Found a screen resolution bug

I have a line going up the screen to a point its about 2 inches from the top at all resolutions except for wide screen ones. This means that It would mess with any math done in the program and boundaries set up for screen edge detection with the bullets. So The game will only support none wide screen resolutions just as long as they are the standard ones. Unless I can figure out a procedure to fix this. If you go wide screen it puts it up closer to the top of the screen which means less of a distances between the center and top. So things will look like there happening faster when in fact its the same speed but it is screwy.
