title: Responding to the onmousemove event outside of the browser window in IE
body: <p>In Internet Explorer 7 <em>body onmousemove</em> or <em>document.onmousemove</em> events only seem to fire while the mouse is inside the browser window, not when it's outside. Yet in Firefox the <code>onmousemove</code> event is called correctly when I move outside of the browser window.</p>
  <p>How can I setup an event to be called outside of the browser window in IE?</p>
  <p><a href="http://maps.google.com/" rel="nofollow noreferrer">Google Maps</a> does this in IE. If you hold the mouse button down and move the mouse outside of the browser window you can see that the map still moves.</p>
