Hi Abdullah,

actually, I find that hard to believe. O'Reilly's JS Definitive Guide,
which rarely errs on such matters, reveals that the parent property of
the window object is in fact read-only. Mozilla ignores all attempts to
overwrite this property, IE6 throws an error ("Not implemented").

Here is the code I tried:

-----------[code]-----------

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title> title me </title>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript">
<!--
function shutDown() {
	window.parent = true;
	self.close();
}
//-->
</script>
</head>
<body>
<a href="javascript:shutDown()">Click</a>
</body>
</html>

-----------[/code]-----------

Do you have a functioning bit of code for this ?
