to do this just edit the navbar template and it should work u have to replace this code here
<script type="text/javascript">
<!--
function log_out()
{
ht = document.getElementsByTagName("html");
ht[0].style.filter = "progid:DXImageTransform.Microsoft.BasicImage(grays cale=1)";
if (confirm('$vbphrase[sure_you_want_to_log_out]'))
{
return true;
}
else
{
ht[0].style.filter = "";
return false;
}
}
//-->
</script>
