Hi,
I am having issue in onbeforeunload event while loading div
below is the detail of my issue. 

1. Create aspx page.
2. write below code
 
 jQuery(document).ready(function() {
 alert("I am ready");
 window.onbeforeunload = function()
 { 
 alert("before");
 $('.defaultDOMWindow').openDOMWindow({ 
 height:175, 
 width:300, 
 windowSourceID:'#divBISSurveynew' 
 
 }); 
 } 
 }); 


<div id="divBISSurveynew" style="display: none;" class="defaultDOMWindow"
>Hello Survey!</div>

on closing page survey div should popup. 

I am using jQuery JavaScript Library v1.3.2 on windows OS


1) Same window works fine on onload 
2) onunload and onbeforeunload alert works fine but loading <div> is not working...

Thanks in advance for looking into it.

Thanks,
Jayaradha
