I recently received an update for Parallels 8, and since it installed Parallels has gotten unstable. Version info: Build 8.0.18354 (Revision 823166; December 4, 2012) Seems to crash for no apparent reason; can't print from QuickBooks, and other odd issues. Is it possible that you broke something while trying to fix something else? This is on a MBP with Retina display, 8 gig's of RAM. Thanks, Cork
