title: Target.count causing an Overflow error
body: <p>I have <code>Worksheet_SelectionChange</code> function. In the first line I wanted to condition that if more than 1 cell is selected then exit. 
  I wrote:</p>
  
  <pre><code>    If Target.Cells.Count &gt; 1 Then Exit Sub
  </code></pre>
  
  <p>However, when I select the whole worksheet, I get an error message:
  "Run time error 6 - Overflow"</p>
  
  <p>It seems like <code>Target.Count</code> can't handle such large numbers ?</p>
  
  <p>What can I do to get around this?</p>
