full screen with no scroll bars,.

This may seem simple enought, but I can't diaply a full screen page with no scroll bars.  When I indicate scrollbars=0, the scroll area still appears on the right but without the slider.

Here is the code below.  Can someone either fix this code, or suggest a new script that works properly?

<SCRIPT LANGUAGE="JavaScript">
<!--
function FullScreen(){
if (window.screen){
var hori=screen.availWidth;
var verti=screen.availHeight;
window.open('LoginForm.asp','FullScreen','width='+hori+',height='+verti+',fullscreen=1,scrollbars=0,left='+(0)+',top='+(0));
}
}
// -->
</script>
