First off, kudos Parallels. I am so glad I went ahead and purchased a license. Helps me support my mother who is still a Windows user as well as the few apps I must run in windows (a few activeX websites ) Seamless drag and drop from desktop to desktop is so nice. However, I cannot get Parallels to use the Boot Camp partition. It always BSODs around mup.sys it appears. Any help or ideas? I have the tools installed and did that before attempting my first use. I have been selecting the right profiles I believe. No luck. Fairly standard Mac Pro. 3GB RAM and stock 250GB drive with 2 X 2.66Ghz procs.
