I find it quite irritating when SC4 decides that I am done playing for the day! I don't know how specific I can be, but how come the game crashes randomly after a certain period of time? I am running SC4 on Vista, and I hear a certain sound coming from the hard drive, and that is when I know the game is about to crash. When I hear it, the game freezes, I can't save quickly, and within two seconds, my desktop appears. Are there patches or any fixes for this problem? Thank you very much.
