Prior jQuery UI Dialogs become nonresponsive after opening a new Dialog
<p>I'm having issues with multiple jQuery dialogs.  The first one opens fine - is resizable, draggable, etc.  However, when I open a second the first becomes unresponsive to dragging/moving/closing, even after the second one is closed.  What is the reason for this and how can it be fixed?  </p>

<p>According to the jQuery documentation this should work fine (since stacking is supported).</p>
