You can use .opener to open a window without toolbars, menubars, etc. To do this:
<script language="javascript" type="text/javascript">
function open_it(){
//this opens a new window without toolbars, menubars, etc.
lovechild = window.open(file_you_want_to_open.html", "lovechild","height=679, width=1200,resizable=0,menubar=0,toolbar=0,location=0,directories=0,scrollbars=0,status=0")
//this sets the opener of the first opened window to the new window you just opened
this.opener=lovechild
//this pauses, then closes the window you first opened
setTimeout("self.close();",5000)
}
</script>
