Hi Dina,

<script type="text/javascript">
<!--
newwindow=false;
function fenster(url,breite,hoehe)
{
if(newwindow&&newwindow.closed==false)
newwindow.close();
var l = (screen.availWidth - breite);
var t = (screen.availHeight - hoehe);
newwindow = window.open(url,"newwindow","width="+breite+",height=" +hoehe+",left="+l+",top="+t+";");
newwindow.focus();
}
//-->
</script>

Und hier noch der Link dazu:
<a href="seite.htm" target="_blank" onClick="fenster(this.href,300,300); return false;">Link</a>

Gruß

Kurt
