title: Pushing updates from event log to webpage not working in IE8
body: <p>In my MVC4 application I have some code to push a new entry in the eventlog to a webpage with SignalR. This code works in FireFox, but in IE8 when a new event is added to the event log the debugger pops up with <code>Error: Object doesn't support this property or method</code> and stops at the following code:</p>
  
  <pre><code>this.notifyListeners = function (queryName, evt) {
          registeredListeners.forEach(function (item) {
              if (item.queryName === queryName) {
                  item.listener.newEvent(evt);
              }
          });
      };
  </code></pre>
  
  <p>When I step over this method the debugger closes and the event is shown on the page. Why does this happen and how can I workaround this?</p>
