I've bought Parallels and continue to like its performance for all kinds of guest systems on my dual core Intel laptop. But I also encountered many problems. The biggest problem for me is every time the guest system (any OS) crashes when the host system (Win XP) wake up from sleep. It doesn't bring down the host system. But I need to restart guest system and it wastes my time. Is it a known bug? Can Parallels team fix the problem?
