I've been using Windows XP under Parallels on a MacBook Pro. One day, Parallels started closing the guest OS after a certain period of inactivity, so I was always having to reboot Windows. This morning, I went to start Windows, and now it won't even start. It looks like it's going to boot for the first 2 seconds, then the entire Parallels window turns black. A few seconds later, it gives up, and takes me back to the guest OS configuration screen. Any ideas on how I can get my guest OS to boot? Thanks, Christian
