title: IE 10 popup window disappear behind main window
body: <p>I have a application wrote for Internet Explorer, right now I have a IE10. 
  My problem: when i clicked at hiperlink, popup window isn't show correctly- popup window opening behind main window, but window exist but under the main page- when I click at windows bar the popup look ok.
  One way to repair this is a reseting Tabs from Tools/ Internet Explorer but this is not for always and I can't force client to runing this all the time.
  In this popup window I don't have much  JS code and i think that is not depend of this.
  Anyone had this problem and know sth about this?
  Regards
  Mike </p>
