title: Worksheet change, selection change, before doubleclick stop working
body: <p>On my sheet I have Worksheet change, selection change and before doubleclick macros.
  They work like a charm but sometimes they stop working. They don't trigger at all, even when I do a thing that must trigger them.</p>
  
  <p>When they stop to trigger :
  1. If i write a macro like</p>
  
  <pre><code>sub test
  msgbox "hello" &amp; application.EnableEvents
  end sub
  </code></pre>
  
  <p>and play this macro, it works and show me "hello TRUE".</p>
  
  <ol start="2">
  <li><p>If I add msgbox "hello" at the first line in worksheet change macro, and test it with a thing that must trigger it, nothing happen.</p></li>
  <li><p>If I close the workbook and reopen it, that works again like a charm.</p></li>
  </ol>
  
  <p>I don't know what can stop these macro. I though that if application.events return "TRUE" then these macros must trigger (and eventually cause errors, but they must trigger).
  What could I do to test what stop them sometimes ? What could it be ?</p>
