title: Trap the Worksheet Unprotect event in Excel
body: <p>I have a protected Excel worksheet, without a password. 
  What I'd like to do is trap the event that a user unprotects the worksheet, so that I can generate a message (and nag 'em!). I can setup event checking for the application, for when new workbooks are opened, etc., but not for Unprotect.<br>
  Does anyone have an idea?</p>
