[DM-MUG] odd Q ref rectangle on my screen

[Victoria L. Herring]

This is on my MacPro and it doesn't prevent anything but it prevents 
the cursor from going outside the rectangle without moving the 
rectangle.

I hit some keystroke on my keyboard -- up jumps a black rectangle on
top of the screen = only the 4 borders show but I can't move my
cursor out of it without either expanding the lines or moving the
rectangle...I pushed escape and nothing happened. I can't restart
due to other processes going on right now -- I seem to remember this
may be something in Leopard but don't know what keystrokes I hit so I
can't just go to that program and fix it...any ideas???
