title: Excel not reporting a circular error
body: <p>There's lots of questions about Excel reporting circular calculation errors when none exist, but I have the opposite problem: I have a sheet that my Excel says is fine, but when I open it on another machine it reports a rather obvious circular error formula.</p>
  
  <p>Excel 2010 Pro Plus. Error checking is turned on in Options. When I try it manually by clicking Formula->Error Checking, it reports "error checking is complete" with no problems reported.</p>
  
  <p>Anyone see this before?</p>
