Maybe this works...
if you can see that, the big gray box at the bottom is where I had my panel, the focus, and my target. The char pane in the upper left corner and the Blizz main action bar are still there, and I have looked everywhere in the Blizz interface menus to figure out where to hide them.
It was fine until 3.3, but its blocking chat and half my buttons, and I can't make it go away!
Thanks for any help!
