I think changing the background but leaving the current value "as is" is better than changing the value. That way you
indicatethat the value is there (and can be retrieved with copy/paste) but that you can't show it (and perhaps add a
pop-uphint when the mouse is moved over the cell)<br /><br /><div class="gmail_quote">On Wed, Jul 28, 2010 at 8:19 AM,
