title: Socket.IO chat in html popup window
body: <p>I try making Socket.IO chat using generated popup window for private message.
  I use windows.opener var in popup window code to acess variables and functions in main page. In Firefox and Chrome window.opener.socket.on(...) function successfully start from popup window code, but IE9 wont. Node.js server in background send and receive events. I use following code:</p>
  
  <pre><code>     //in index.php
      var socket = io.connect('http://localhost:8080');
       //other code
      $("#users .user").live('click',function(){
      //other code
      popUpWin[client_id]=window.open('private.php', client_id, 'toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbar=no,resizable=no,copyhistory=yes,width=300,height=400,left=' + left + ', top=' + top + ',screenX=' + left + ',screenY=' + top + '');         
      //other code        
      });
  
  
      //in private.php
      //other code
      window.opener.socket.emit('popup',window.opener.client_id);//This work!         
      window.opener.socket.on('private_message', function (data) {This not work, private message event is send!
          $("#private_data_recieved").append('&lt;div&gt;&lt;b&gt;'+data.nick+':&lt;/b&gt; '+parseString(data.message)+'&lt;/div&gt;');
          playSound();                        
      }); 
          //other code
  </code></pre>
