Just stumbled on a potentially related problem (well, at least in a sense of 
messageboxes getting created from JS), so I think I'll throw it out here in 
case it's useful for this discussion:

<html>
  <head>
    <title>Weird crash</title>
<script type="text/javascript" language="javascript">
function processMemo( theForm )
{
   confirm("Crash");
   theForm.submit();
}
</script>
  </head>

  <body>
    <form action="http://mail.rochester.edu/~mo002j/test" method=
    "get">
      <input type="text" onblur=
      "javascript:processMemo( this.form)"> <input type="text"
      onblur="javascript:processMemo( this.form)">
    </form>
  </body>
</html>
