I've been using Safari in full screen mode since Lion introduced the feature and have gotten used to moving the mouse to the top of the screen to see the menu bar and bookmarks bar. This worked on Mountain Lion up until today when it just suddenly stopped working. I was wondering if anyone else has had this issue and resolved it? I tried relaunching Finder, killing the menubar from Terminal, restarting, and even reinstalling Mountain Lion (not clean install). I have a Mid-2009 15 inch MacBook Pro if that matters. Thanks for any help.
