My video is playing full screen and I can’t see the Player. How do I stop the theme?

To reduce a full screen image or video window so that you can find Launchpad and Designer, double click on the image. This will reduce the image/video player into a window. You can then use the standard window icons to move, reduce or close the window and access the other Launchpad controls.

You can also use the ‘Escape’ key if the video player is the currently selected window.
