 // -------------------------

 // window with passed 
 // features (FLASH MX)
 // ------------------------- 
 MovieClip.prototype.centerPopup = function( theUrl,title, w, h, features) 
 {
   var sysW = System.capabilities.screenResolutionX;
   var sysH = System.capabilities.screenResolutionY;
   var centerx = Math.round((sysW/2)-( w/2));
   var centery = Math.round((sysH/2)-( h/2));
   getURL("javascript:void(window.open('" + theUrl 
 + "','" + title + "','width="+w+", height="+h+", left="
 +centerx+", top="+centery+",screenX="+centerx+", screenY="
 +centery+"," + features + "'));"); 
 NewWindow.focus();void(0);
 
 if(w.indexOf("%")!=-1){
 w = sysW*parseInt(w);
 }
 if(h.indexOf("%")!=-1){
 h = sysW*parseInt(h);
 }
 }

on bttn:


 on (release) 
 { 
 centerPopup("http://www.html.it","html","menubar=no"); 
 }

This works great in the Firefox browser.
In IE it will give me a popup, LEFT TOP 400*400
somehow…

Someone with a solution to make the same what FF does?
Thnx in advanced.
