I just used bootcamp to install the windows XP partition on my macbook yesterday (2ghz 1 gig ram) and I've been wanting to try out Half Life 2 so I bought it off of Steam. The game works fine...until I go through that door right after you jump out the window. The game pauses to load and then it starts again for about 2 second and crashes. It happened 4 times on a variety of settings. Anyone know how I can fix this?
