Hi, Jeffrey ~~ No, not Safari. The background display that comes on when you turn on computer. I guess, the desktop? Has background, menu bar at top and dock on bottom. Has been the same for two years. Was working yesterday and hit something and the desktop expanded to point where menu bar isn't visible and dock isn't visible and both left and right sides of desktop display aren't visible.
As though the whole desktop expanded by about 40-50%. I thought I must have accidentally hit full screen. I hit escape. Nothing. I went online and found several things for "how to return desktop to normal size." I tried everything I could find. Nothing. The menu and dock (and sides) are still "there" but I have to mess with the cursor forever to get one or the other to come into view. I tried zooming in. Icons and stuff were more concentrated but still can't see top, bottom, sides. I should note that the icons and lettering on things on desktop did NOT increase in size so it doesn't work to resize those. And, I checked to make sure "never hide" the menu bar in systems settings first; it's on "never hide." I know this has got to be something simple but I don't know what it is. Appreciate all help you can give me.
Thanks,
Gale
