title: Internet explorer 7/8 support of normal event passing, no need for window.event?
body: <p>It is common knowledge that Internet explorer does not support event passing to event handler functions like this one:</p>
  
  <pre><code>function clickHandler(e) {
    // e is undefined in IE
    e = e || window.event;
  {
  </code></pre>
  
  <p>For my surprise today, I found out that actually it does. I forgot to do this "e = e || window.event" trick in one of my functions, but it was working in IE8!</p>
  
  <p>I did some tests with IE developer tools, the e object was fully defined and it was so even in IE7 mode.</p>
  
  <p>My question is, should I drop the window.event stuff entirely since I do not care for IE versions prior to 8?</p>
