well, I removed the preference files, and still had a crash the next time I played. As far as the crash logs go... I have a ridiculously long crash log. I don't know what to make of it, but it goes on, and on, and on. There are tons of errors over a really long period of time. I think at least some of the errors relate to the problems that DotA has on the mac (doesn't play some sounds, for example). Should I look for anything in particular?
Do you think it's possible the game is crashing because of something with the video card (GMA 950)? I know that it's under more strain in leopard... and the computer does get ridiculously hot playing war3... maybe the crappy, crappy GMA 950 just can't keep up?
