I have parallels 6 and when I tried to open it today (I havent opened it since the most recent update) I realized that it gets stuck on the loading animation (Transparent grey bubble with a load ring and "Parallels Desktop"), no error is given. It'll sit here until I quit the application. I can access preferences, add virtual machines, everything except open the ones I've already installed. I'm running the latest version of OSX Leopard. Has anyone had a similar issue or know of a way to help?
