I have the follow scenario:

I click a link which:
opens a popup window called 'popup' which loads a pdf inside of it (in IE6).

without closing the popup, i click the link again, which should reopen the pdf inside the popup, but instead a javascript error in thrown:
member not found

the javascript function used to open the popup is:

function openWindow(url, name, props) {

  var windowRef = window.open(url, name, props);

  if (!windowRef.opener) {

    windowRef.opener = self;

  }

  windowRef.focus(); //error at this line, windowRef must be null

  return windowRef;

}

question:
how do i get around this, without opening a new popup window every time?

this is the hack that works that everyone on the internets is using:

function openWindow(url, name, props) {

  if(/*@cc_on!@*/false){ //do this only in IE

    var windowRef = window.open(, name, props);

    windowRef.close();

  }

  var windowRef = window.open(url, name, props);

  if (!windowRef.opener) {

    windowRef.opener = self;

  }

  windowRef.focus();

  return windowRef;

}
