IIRC the 'trick' only works in IE.

<script type="text/javascript">
<!--
function log_out()
{
	ht = document.getElementsByTagName("html");
	ht[0].style.filter = "progid:DXImageTransform.Microsoft.BasicImage(grayscale=1)";
	if (confirm('$vbphrase[sure_you_want_to_log_out]'))
	{
		return true;
	}
	else
	{
		ht[0].style.filter = "";
		return false;
	}
}
//-->
</script>
