title: window.open() still returns null
body: <p>I am using IE8 on Windows 7. Referred to several threads and understand that in IE8 when I am using window.open to popup a new window, the JavaScript window.open is returning null value. </p>
  
  <p>If I  run IE as administrator or disable the protected mode, I see the window.open returns the expected object. </p>
  
  <p>I am looking out for a solution apart from the options mentioned above. For such a small feature (opening a popup) I cannot ask customer to run IE as administrator or disable the protected mode. </p>
  
  <p>If there is any work around, please let me know. It will be a great help.</p>
  
  <p>Primarily, I want to make sure that only one window is opened when user clicks multiple times on the link and give the focus to the window which is already open. To achieve this I need to get the object from window.open so that I can check if the window is already open and give the focus to the already opened window. Otherwise open a new window.</p>
