I ported Blacklight: retribution to the Mac. It works fine, although the framerate is not fantastic. However there is this one issue with the mouse that I need help with. The mouse is not properly tied to the fullscreen window, and so when I am playing, looking around with the mouse, the mouse will run into the "walls" of my desktop instead of being tied into the game like other FPS games, and I will not be able to look anymore in that direction. Can I fix this?
