title: Repeated freezes/crashes in Excel for Mac VBA Editor
body: <p>Something's causing VBA Editor to crash in Excel for Mac.</p>
  <p>All used to be fine.</p>
  <p>Then I started to get a perpetual freeze, or a complete crash and exit, when typing (often, I think, but wouldn't swear, towards the end of a line).  It would usually survive a few (but not many) keystrokes.  I hadn't been trying to do anything out of the ordinary or especially advanced.</p>
  <p>I assumed some corruption in the file.  I tried deleting large areas of it. I tried porting to a different file.  With no improvement, I suspected Excel, so uninstalled and reinstalled.  The problem persists.  I've taken to writing code in word, copying it in, and correcting it - with regular saves.</p>
  <p>It's now refusing to save the file, claiming 'errors were detected' and that it would 'minimally save the file' - but where it says it's saving it to doesn't exist.  All snail-like limping on has ground to a halt.</p>
  <p>Clearly something went awry somewhere at some stage.  Even if I could have limped the final 3% to complete a module with seven or eight macros, something is clearly wrong and ought to be put right.</p>
  <p>I'm out of ideas.  This might be obvious to people who know more about this sort of thing the I do: Where or what might the problem be, and what do I need to do to get the VBA editor working like a dream again?</p>
  <p>Thank you</p>
