Jquery older version works but not newer
<p>This fiddle <a href="http://jsfiddle.net/mjmitche/U5BuM/" rel="nofollow">http://jsfiddle.net/mjmitche/U5BuM/</a>  works in jquery 1.3.2 but not the latest 1.5.1. It was created using an old tutorial. Do you know how to make it work for 1.5.1?  </p>

<p>Should I expect a lot of problems like this while learning jquery?  What's the best way to deal/ learn about these conflicts as I'm trying to learn jquery?</p>
