title: FullScreen works onclick but not onload
body: <p>I'm trying the code from <a href="http://www.paulund.co.uk/javascript-full-screen-api" rel="nofollow">here</a> to start fullscreen mode. It works if executed <code>onclick</code> , but not <code>onload</code>. (I've also discovered that setting an <code>alert</code> before it will disable it unless the <code>alert</code> is clicked immediately.) So perhaps the problem is that sometimes the browser isn’t 'ready' for fullscreen.</p>
  
  <p>So what is the last event fired when a page is completely ready? Or is the solution different?</p>
