I have migrated to a new MacBook Pro (15" Retina Haswell), but Parallels isn't working at all. When I launch it, the icon shows in the Dock, but the Windows are not visible. Clicking on any option doesn't result in any visible windows, although the menubar shows Parallels Desktop. It's also active in Activity Monitor. When I try to Quit it, I get the "you have an open dialog" BONK sound. I have attached a second monitor, used Expose, and done everything I can think of to figure out where the Windows are and how to get going, but I'm at a loss. HELP?!?!
