Closing the video output windows by clicking on close button not working
This one is tested on several Windows 7 and 8 installations on several PC setups.
I usually use the non integrated video in the interface, VLC (xxx output). When using this, only the mini- and maximize Buttons in the video window are working. Clicking on X button to close just the video (not VLC at all) does not work. So the only possibility to close the video window is by clicking on stop in the interface window.
This definitely worked fine up to version 2.0.8, definitely not working since 2.1.x up to 3.0 nightly.
