title: Does Flex dispatch an event when a popup is brought to the foreground?
body: <p>Is there an event dispatched when a modal is brought to the front in Flex? Basically there are two times when I would want to listen for this event:</p>
  
  <ul>
  <li>When the modal is first created (although in theory creationComplete / show / etc.. could suffice here)</li>
  <li>When the user brings a modal that is not in the front to the front by clicking on it.</li>
  </ul>
  
  <p>In my case the popups I am working with are descendants of TitleWindow and listening for focusIn does not seem to work reliably.</p>
