When in parallel and clicking the red (close) button in error, it would be very nice to have a warning asking the user if he wishes to close or stay in parallel. Since parallel window is set to look the same as a Mac, it is easy to close a Mac screen by clicking the red button, while in parallel, however, click on the red button close parallel rather than the default open window. A warning would be nice before activating the command .
It is configurable in all Parallels Desktop versions. Just open VM configuration -> Options -> Startup and Shutdown options. Please refer to Parallels Desktop Documentation for more details. Just press (?) button on the VM configuration window.
This was a life saver!! I had real problems with my staff closing the window (hitting red button) with no warning!! On window close>>>Ask Perfect!
