I am using windows 7 and I am having some problems. First, my brightness/gamma sliders don't do a thing...or it doesn't seem too. I have already made my cl_gammaramp 0. Also, after quit ns the game freezes and I am stuck with the background wallpaper, then i have to ctrl alt delete and end the hl.exe process to get ns to fully close.
