Hello again, another question!

I have a little window open code (that works in normal HTML).
Here's the code:
-----------------cut
Nowe=null;

function Otworz(s,w,src) {

var Xpos=((screen.width/2)-(s/2));
var Ypos=((screen.height/2)-(w/2));

Nowe=window.open('main.html','',
'toolbar=no,
menubar=no,
location=no,
personalbar=no,
scrollbars=no,
status=no,
directories=no,
resizable=no,
width='+s+',height='+w+',
left='+Xpos+',top='+Ypos);

Nowe.focus()

}
-----------------cut

It works perfectly in browser (as HTML), but when inserted into 3DFA as Javascript element, it doesn't seem to work (but "Compile" button in Javascript window reports no problems...). What shoul i do? I can't go for "Open URL", beacuse it'll be an presentation (EXE), not the web page...

HELP!
Thanks in advance..
