For me it did not work (even reinstalling PT).
Incidentally, how would it work? I thought the windows of the Windows 8 would be on the desktop of the Mountain Lion.
I tried again and gets "The virtual machine display configuration could not be applied. Please try again or contact the Parallels support team for assistance."
I tried again, and again, and again. The error was fixed, but coherence don't works.
I followed the guidance that support gave me for chat and neither worked.
