title: Member not found error in java script
body: <p>The below code for opening and closing a window is throwing a java script error 'Member not found'. This does not happen in all machines but for certain users with IE 8. 
  winobject.blur() in the following code is throwing the error.</p>
  
  <pre><code>var winobject=null;   
  winobject = window.open('URL','Name',"width=1,height=1,top=2000,left=2000");
  if(winobject!=null){
      winobject.blur();
      self.resizeTo(screen.availWidth,screen.availHeight);
      winobject.close();
      ...
  }
  </code></pre>
  
  <p>Any help or suggestion to resolve this issue?</p>
  
  <p>Some additional observations- This issue only occurs when a window with the 'Name' already exists. Lets say if the user has already closed the pop up window that was already opened then the code will run fine. Also if I add one more window.open under the current one then no exception gets thrown when blur() is invoked. Not sure why though ?</p>
