I've got an old Windows 2000 VM that I only use every six months or so. With the latest 6.0.12090 build and Mac OS 10.6.8 accessing Mac volumes have become very slow, with, for instance, Windows Explorer taking 5-10 seconds to start populating displaying a folder. Unfortunately I don't know if it is the Parallels version or the Mac OS version that is causing the problem, but it sure is annoying!
