Has been working perfectly for months. Then last night I noticed that Jupiter surface was not displaying. Weird.
Clicked Settings icon, turned on planet surfaces display (it had somehow turned itself off without me making any change), then "Done" and back to main screen. Uh-oh, no icons along bottom of screen. Now I cannot access any menus at all so I am limited to only scrolling, zooming, etc.
Have installed all available SS updates, but cannot access settings to confirm SS version number.
