Hi

Don't use the same projection matrix to draw the crosshair and the rest. I have worked for about ten years on my own first person shooter, I think that I know what I'm talking about ;) What happens when you comment the few lines before glLoadMatrixf?

Rather use GLU.createGLU(GL) than new GLU().

Use NEWT instead of AWT if you want fullscreen support on all supported platforms.
