Issue with Full Screen Toggle
In Muséik 3.0.2 there is an issue with the full screen toggle function. When you press ESC the output display goes to full screen mode, but it is not possible to toggle the output display back to a minimized view. Instead, pressing the ESC key will toggle between a full screen display with the menu bar across the top and a full screen display without the menu bar.
To remove the full screen display it is possible to minimize the display and store it in your dock.
Or it is possible to re-start the program, in which case the output display will appear in the minimized view.
