How to unlock protected document

I opened an existing document I had saved in Word and when I tried to
make revisions, the message came up that the document was "locked".
When I went to "help" to see how to unlock it, it says to go to the
Protect Document pane and click on "Stop Protection". However, when I
go to this pane, there is no option to "Stop Protection" - help!

Sounds like you need to talk to the folks in the Office or Word newsgroups,
not us Vista folks.
