Inschi jelii, Martin Honnen,

This is only possible precisely with NN4+ which provides
  window.outerWidth/outerHeight
while IE doesn't provide that:
function openCentered (url, width, height) {
  if (document.all) {
    var x = window.screeLeft;
    var y = window.screenTop;
    var w = window.document.body.offsetWidth;
    var h = window.document.body.offsetHeight;
  }
  else {
    var x = window.screenX;
    var y = window.screenY;
    var w = window.outerWidth;
    var h = window.outerHeight;
  }
  var cx = x + Math.round((w - width) / 2);
  var cy = y + Math.round((h - height) / 2);
  return open (url, null, 'left=' + cx + ',top=' + cy + ',width=' + 
width + ',height=' + height);
}
//Example
openCentered('http://JavaScript.FAQTs.com', 300, 300)
