Sorry, it seems like a silly question, but...

How do I close the Task Manager dialog box?

There is no close "X" button in the upper right hand corner, no "File" dropdown menu, and nothing happens when I right click the task bar box (which is blank except for an icon of a computer).

The Task Manager itself works fine. The "End Task", "Switch To" and "New Task" buttons all work. I just can't close the Task Manager dialog box.

Any help is appreciated. Thanks.
