hi, i experience regular freeze of parallels using win2K as a guest OS. I don't know exactely why it happens, it seems it's after i left my MBP unused for a certain amount of time (although it is not in sleep mode). Parallels in itself sometimes looks like it's still working (tooltips appear), but win2K is freezed, and the only solution is to force quit Parallels. It also crashed once. If you need more info, just tell me. In the mean time, here is a crash log. I also have two other problems : shared folders don't work (i can't see them in the network), and custom resolution neither (seee this screenshot).
