For those that want to play this game in 'Window Mode' or your Norton Internet Security keeps freezing the game everytime you want to play online then here's how you do it. Use Notepad and open up "autoexec.cfg" which is found in "C:\Program Files\Fox\Aliens vs. Predator 2\". Now type in "Windowed" "1" including the speech marks. Now run the game and it's in Window Mode and you can fix that annoying Norton problem too. Enjoy.
