title: How do I get rid of the "cannot empty the clipboard" error?
body: <p>Right now, I'm getting it in Excel 2007, but I've gotten the same error in pretty much every version of Excel I've used since 97.  The only discernable similarity is that happens on my office PC.  It's never bothered me on my home PC.</p>
  
  <p>In Excel 2003, I was able to mess around in the clipboard options until it went away.  In 2007, though, the options seem to be seriously limited and generally useless.  Google wasn't much help, either.</p>
