Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over.
When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...
