Allow recording to continue with guest screen minimized.

I would like to see the screen recording function continue to work if the screen to the Guest machine is minimized on the Host station.  My Support team will often record a full day of actions on a guest station to try and get a recording of an irregular\elusive error message.  However having to keep a window open to feed the recording isn't a practical use of the screen.  Also the recording (when screen is minimized) continues to capture the mouse movement, so capturing the whole screen makes sense to me.
