Since the most recent upgrade I've had the odd phenomenon of the side panels, top menu and the filmstrip going missing for no reason that I can understand. Sometimes I can get them back by switching modules from the keyboard (Cmd-Alt 1 etc), sometimes I have to quit and restart the program. The screenshot shows how it looks.
Is this a known problem?
