Hi All, As well as the performance hit when using Vista in Parallels, is anyone having issues with their macbook pro fans constantly reving up and down. Is Vista causing my system to overheat? I know it overheats due to bad power management in bootcamp due to lack of power management drivers but i thought with Parallels, it was Parallels and OSX that managed the power management, not the guest OS. Before people ask why I am installing Vista, I am a fan of mac security but need the occasional windows application, and Vista is just that little bit more secure than XP. Greg
