in IE, it works fine, the window can be pop-up, but in Netscape, no response at all, why?
I wouldn't use a FS command for this, all you need is:
In the head part of your html file add this:
<SCRIPT type="text/javascript" language="JavaScript">
<!--
function newwin(location,name,w,h)
{
var scrw=(screen.width/2)-(w/2);
var scrh=(screen.height/2)-(h/2);
window.open(location,name,'scrollbars,left='+scrw+',top='+scrh+',width='+w+',height='+h);
}
//-->
</SCRIPT>
