permission denied when tried to close opener window in ie

Hi friends,

I would feel very thankful if someone has answer to this question. I have a window and from that i open up a popup and when i call the popup both the popup and the parent should be closed. So i wrote a methos in the opener window itself which
{
if(popupWindow!=null) popupWindow.close();

self.close();

}


Now i called this method whenever i clicked cancel in the popup window:

window.opener.closeWindows();

this is working fine in most of the browsers, except in xp systems with service pack installed. even there this is working except a "permission denied" script error.

If someone had the same problem and solved it, can you please help me.

Thank you in advance.
