title: Excel Macro-Enabled workbook (.xlsm) macros disabled and no obvious way to re-enable
body: <p>I'm having trouble with Excel macros being disabled in a macro-enabled workbook.  I have an Excel 2003 template file (.xlt) that includes macros.  I then do the following:</p>
  
  <ol>
  <li>Open the Excel 2003 macro enabled template workbook (.xlt) in Excel 2007/2010</li>
  <li>Save the workbook as an Excel 2007 macro-enabled workbook (.xlsm)</li>
  <li>Close and open the workbook in Excel 2007/2010</li>
  </ol>
  
  <p>Then the macros are disabled and there is no obvious way to enable them.</p>
  
  <p>The same problem seems to be described here: <a href="http://www.sqldrill.com/excel/miscellaneous-excel-subjects/872432-excel-2007-macros.html" rel="nofollow">http://www.sqldrill.com/excel/miscellaneous-excel-subjects/872432-excel-2007-macros.html</a></p>
  
  <p>I’ve tried saving to a ‘trusted location’ and the other suggestions in that thread but the same problem occurs.</p>
  
  <p>Has anyone else come across this problem?</p>
  
  <p>Thanks,
  Tom</p>
