title: Is there a cross-browser solution for monitoring when the document.activeElement changes?
body: <p>I'm really looking for something that works with all current popular browsers (IE9, Chrome, Firefox, Safari) and all the way back to IE8.</p>
  
  <p>Although, I've been looking for a way to set focus on a Flash move object after it has lost focus, I've found that all historical ways of doing this fail.  I assume it is yet another security issue.</p>
  
  <p>So, I'm now looking for how to monitor change events of some sort for the document.activeElement (though "change" doesn't really occur).</p>
