It would be great if Parallels Desktop had an option to pause the VM whenever you either minimised the window or hid the application (a user settable option for this would be fantastic). Virtual PC used to have an option for this, and it made working in two platforms at once much more manageable. It would also be good if PD could stop using 3-4% of my CPU when it's paused... there should be no reason at all for PD to be using CPU cycles in this state, right? Not a show stopper, but it's a bit strange. Would anyone else find this useful?
