I'm getting a strange behavior with yui Panel in a IE-only scenario.  I'm instantiating a Panel and setting the body of the Panel dynamically via an standard ajax call to the server.  The returned content looks something like this:

<div>
  ..blahblahblah
</div>
<script type="text/javascript" src="blah.js"></script>

I set the body of the panel via panel.setBody( o.responseText ).

The problem is that in IE, the <script> tag doesn't get evaluated.  I'm not sure if this problem have anything to do panel or whether the problem is a simple browser issue.  Anyone know what might be the cause?
