intanto quello che hai scritto e neanche ti serve il java, quindi che tu non ne sappia niente ha poca/nulla importanza....... cmq prova cosi

codice:
<script type="text/javascript" language="JavaScript">
<!--
function winOpen(URL, windowName, width, height, left, top, resizable, location, menubar, scrollbars, status, toolbar, directories){
var windowFeatures;
windowFeatures = '';
if (width != '')
windowFeatures = windowFeatures+'width='+width+',';
if (height != '')
windowFeatures = windowFeatures+'height='+height+',';
if (left != '')
windowFeatures = windowFeatures+'left='+left+',';
if (top != '')
windowFeatures = windowFeatures+'top='+top+',';
if (resizable)
windowFeatures = windowFeatures+'resizable,';
if (location)
windowFeatures = windowFeatures+'location,';
if (menubar)
windowFeatures = windowFeatures+'menubar,';
if (scrollbars)
windowFeatures = windowFeatures+'scrollbars,';
if (status)
windowFeatures = windowFeatures+'status,';
if (toolbar)
windowFeatures = windowFeatures+'toolbar,';
if (directories)
windowFeatures = windowFeatures+'directories,';
windowFeatures=Left(windowFeatures,windowFeatures.length-1);
window.open(URL, windowName, windowFeatures);
}
//-->
</script>
ho aggiunto questo
windowFeatures=Left(windowFeatures,windowFeatures. length-1);
per togliere l'ultima virgola..... vediamo se era quello che gli dava noia a IE8
