I've had some issues is I am running my Parallels Desktop (v7) in full screen mode under MacOS Lion. In order to change "desktops" to another full screen app, or a MacOS space, I must first us the Control-Option keys to release the mouse & keyboard from the Parallels session. Once I do that, I don't seem to be able to get them to re-connect back to the Parallels session. No matter what I do, I can't click on anything in the VM, or send any keyboard commands to it, so I am forced to close the app (suspending the VM) and then restart the app. Does anyone else experience this and have a way to make this more efficient?
