example grabbed quickly from my web page....
<script type="text/javascript" >
<!--
function launch(newURL, newName, newFeatures, orgName) {
var remote = open(newURL, newName, newFeatures);
if (remote.opener == null)
remote.opener = window;
remote.opener.name = orgName;
return remote;
}
function wow() {
myRemote = launch("lots.html", "myRemote", "height=380,width=480,innerHeight=580,innerWidth=500,screenX=10,left=10,screenY=20,top=20,channelmode=0,dependent=1,directories=0,fullscreen=0,location=0,menubar=0,resizable=1,scrollbars=1,status=0,toolbar=0", "wow");
}
function launchwin() {
myRemote = launch("blogroll.html", "myRemote", "height=580,width=500,innerHeight=580,innerWidth=500,screenX=100,left=100,screenY=100,top=100,channelmode=0,dependent=1,directories=0,fullscreen=0,location=0,menubar=0,resizable=1,scrollbars=1,status=0,toolbar=0", "dx");
}
// -->
</script>
sorry this is quick and dirty but with the time difference and the work hrs, I am fading... (this might help)
