title: Member not found IE error (IE 6, 7, 8, 9)
body: <p>Let me just first point out to any IE users right now (this is not a problem in Chrome, Safari or Firefox)  hint hint ;)</p>
  <p>So... I have a issue with my tooltips in IE, I have a <code>onmouseover</code> listener for all the elements which are to be hoverable and then in my <code>mouseover</code> function I have a very basic cross browser declaration as such...</p>
  <pre><code>var event = e || window.event,
      el = event.target || event.srcElement;
  </code></pre>
  <p>I've been having issues with the window object not existing in IE or something, this has been a issue after I added a flag to ignore mouseover's from one element mouseover on the way to the tooltip itself (during the time cycle allowed, 300ms).  In other words the flag is to ignore mouseovers on route to the tooltip from the original mouseover.</p>
  <p>So that logic looks like this...</p>
  <pre><code>loadtip.refMouseOver = function (e) {
  
      var event = e || window.event, el = event.target || event.srcElement;
      //console.log(window); // &lt;-- throws error in IE (Member not found)
      // Reset the lastHoveredRef data.
      tipManager.lastHoveredRef = null;
      tipManager.lastHoveredRef = [el, event];
  
      // true means there is a tip open still, so if no tip is open.
      if (tipManager.tipState !== true) { 
          tipManager.processTip(el, event);
      } else {        
          return; // do nothing
      }
  
  }
  </code></pre>
  <p>The &quot;Member not found&quot; error will occur when I hover from one element quickly to the next in IE with the tooltip still open.</p>
  <p>I read about <code>window.open</code> and close stuff with a try catch but I didn't see how that was relevant.  Any help is greatly appreciated.</p>
