title: Exel crashing on load of previously fine .xlsm sheet
body: <p>Has anyone had this problem - and preferably solved it ;) - in the last 4-6 weeks or so?</p>
  
  <p>I have a .xlsm workbook which has not been changed and has worked fine for 8 years but suddenly it won't load unless I load a very simple workbook first.  I get the splash screen, then it loads to about 50%-60% and then I get a message saying "Excel has stopped working".  Total shutdown and then it tries to "repair" the file until it gets bored.</p>
  
  <p>After loading a random .xlsm file I can then start it ok - it's a bit tedious.  It doesn't get as far as executing any code before it crashes.</p>
  
  <p>Is this something that someone knows about?</p>
