title: Detect mousemove when over an iframe?
body: <p>I have an iframe that takes up the entire window (100% wide, 100% high), and I need the main window to be able to detect when the mouse has been moved.</p>
  
  <p>Already tried an <code>onMouseMove</code> attribute on the iframe and it obviously didn't work. Also tried wrapping the iframe in a div like so:</p>
  
  <pre><code>&lt;div onmousemove="alert('justfortesting');"&gt;&lt;iframe src="foo.bar"&gt;&lt;/iframe&gt;&lt;/div&gt;
  </code></pre>
  
  <p>.. and it didn't work. Any suggestions?</p>
