[Guest]

Hello,
I was on facebook and typing a comment. I thought I was using the Alt key and #3key to make stuff and then all my settings top and bottom disappeared how do I get them back? On this tab I have them? messed up or what?

You may have hit Alt+Enter at the same time. Hitting again will take you out of fullscreen mode if thats what it was.

Or you may have pressed F11...
