Since I am unable to disable Parallels Shared Folders... http://forums.parallels.com/thread1474.html I tried using them, which results in a crash for Windows every time. To recap, I can't disable shared folders, and I can't use them either.
I would also like to add that I experience blue screens when using shared folders, but only when I don't have any shared folders set up in the Parallels machine preferences, but the feature is otherwise active.
