title: jQuery migration from 1.8.3 to 1.9.1 stops working in one line, and I don't know why
body: <p>I was using this code:</p>
  
  <pre><code>http://labs.abeautifulsite.net/archived/jquery-alerts/demo/
  </code></pre>
  
  <p>And it worked fine with jQuery 1.8.3.</p>
  
  <p>Now I changed to jQuery 1.9.1 and it stopped working</p>
  
  <p>Most of my other codes had problems, mostly I had to change .live for .on and it was solved (I don’t know if this was the right thing to do), but with this code, I don’t find the issue.</p>
  
  <p>THIS LINE SEEMS TO GIVE THE PROBLEM:</p>
  
  <pre><code>// IE6 Fix
  var pos = ($.browser.msie &amp;&amp; parseInt($.browser.version) &lt;= 6 ) ? 'absolute' : 'fixed';
  </code></pre>
  
  <p>You can test it in jsFiddle and you can change to jQuery 1.8.3, to see how it works.</p>
