I recently updated from 3 to 4. After restarting Windows XP inside the VM, everything works (almost) fine. If I suspend the VM and resume, Windows is unusable: the mouse is VERY slow (using my MacBooks Trackpad and Mighty Mouse). Also, in general, Coherance doesn't work, Modality sometimes. Full Screen does work. I reinstalled P-Tools more than a few times... Any Ideas? Just re-installing Windows is NOT a solution to me.
