I have been noticing some of the other issues discussed recently, such as really slow times coming out VM (XP) sleep, etc., but lately I have been having a more troubling problem with my mac OSX (snow leopard) crashing on me frequently, while parallels is or is not running, and mac OSX is telling me that it is having "panic" errors. What little information I have found on this problem leads me to believe this is a parallels related issue. I did not have any of these problems with v3 or v4 of parallels. It is extremely disconcerting to have your make display a message saying that there was an internal panic error and you must shut down your computer. Has anyone else seen this or know how to fix it? Thanks!!
