title: Window parent not working in IE 8
body: <p>I have a parent page and a child page.
  By using window.opener.parent property,I am able to read the parent page content and display it in the child page.(There is a PREVIEW button on parent page,on click of which the child page opens up as a popup and displays the content of parent page controls.)</p>
  
  <p>This functionality was working fine in IE7/Mozilla/IE6 but I am unable to locate why its not workin with IE8. Can anyone please help?</p>
