title: Where's the Debug button in Excel VBA error
body: <p>Simple question I haven't been able to find the answer to with Google:</p>
  
  <p>How do I get the "Debug" button to appear in the pop-up that appears when there's a run-time error in Excel 2010 VBA?  I've seen it in the past, but now its missing.</p>
  
  <p>Is this a configuration issue?</p>
