Window.open Question

I have a script that opens a fullscreen popup, but i want to know if u can make it smaller but still have nothing around it but the html page. so its like a fullpage opener but its small.

<script>
<!--
function fullwin(){
window.open("../####.html","","fullscreen")
}
//-->
</script>
<input type="button" onClick="fullwin()" value="Open window">

have you tried?

;dialogWidth:430px;dialogHeight:400px;

im using this with dialogs (showmodaldialog or showmodeless) haven't tried with window.open though

umm...little more help on where to place that please lol :confused:
