This sounds similar to what my user is experiencing, except that in his case restarting Mathematica does not fix it. I don't know of any connection to the Documentation Center (but will investigate). It has happened to him a few times when he has simply left Mathematica open and gone to class, and is not even there using Mathematica. It will be messed up when he returns.
