I'm having a recurring problem. I have both XP and Vista installed (2 separate VM). None are set to autostart. However, quite often when I'm using Vista, XP starts up. Especially when I'm installing a programm or the Parallels tools on Vista. What I do is pause XP when it starts. I would really like to be able to disable this autostart from XP, very annoying. Having a 2nd VM starting uses a lot of RAM and I only have 1.5GB available. I'm using release 3188 of Parallels, the tools are updated on both Vista and XP. Anyone has the same problem ? Or better yet, found a solution to resolve this issue ? Thanks, macdavid
