Translucent gray border around mac screen?

There is a translucent gray border around my mac screen that randomly appeared. It makes it very difficult to move things around and also blocks the close, minimize, and expand buttons. Can I make this go away?

Mac Pro, iOS 7.0.4

The problem is that the expose window is stuck. In order to force a refresh take these steps. 1. launch terminal 2. type killall Dock


For those unfamiliar with terminal, or how to launch it, do this:


type command + spacebar to open your search. Type "terminal" in the search and then "enter" to launch terminal.


You'll see a screen with a blinking cursor. Type:


killall Dock


Hit enter.
