In IE6, ExternalInterface.call method will result in a Javascript error when the flash object is within a html form! (an undefined error)
Steve Kamerman had produced a fix for the bug. (Check his blog)

IE’s implementation of Javascript seems to want to look for “window.yourObject” and not “document.form[x].yourObject”, so his script figures out which form you are in and makes an alias.
window["yourmoviename"] = document.getElementById(”yourmoviename”);

An example of the fix is (assume we are using swfobject also):

<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript" src="swfformfix.js"></script>
<div id="swfdiv">
This is replaced by the Flash movie.
</div>
<script type="text/javascript">
  var so = new SWFObject("myMovie.swf", "myMovieObjectName",
      "200", "100", "6.0.0", "#ffffff");
  so.addParam("quality", "high");
  so.write("swfdiv");
  SWFFormFix("myMovieObjectName");
</script>
