Windows Explorer lost menu, toolbar and address bar

I use Windows Explorer a LOT on my work PC (XP Pro SP-3). I create shortcuts to frequently used network folders. I put those shortcuts in my start menu as well as in My Documents for easy access (and link creation to share documents with coworkers).

A few weeks ago, the Windows Explorer window stopped showing the menus, address bar and tool bars. I simply have a blank window that shows the two panes of folders/files. My Computer, however, remains fine. See attached screen shots.

I've not been able to find a way to restore the views. Any ideas how to do so?

 

I could not open the file because it said it was corrupt, but try using either F11 or Alt-V to bring back the toolbar.

 

F11 worked.
THANKS! Our IT department was all stumped.
