Just installed Parallels Desktop 3.0 and Windows XP Home today on my new iMac running Leopard, 10.5.2. Everything seemed to be working properly until I tried to exit out of Windows by Quitting Parallels. Now the Mac pinwheel is spinning and I can't shut it down, or don't know how to. It's just frozen and seems to be affecting the performance of my Mac side also. Any suggestions on how to resolve this issue and what is the proper way to exit Windows/Parallels?
