title: chaning css background property not working in IE
body: <p>I have an html table:</p>
  
  <pre><code>&lt;table id=mytable&gt;
  &lt;tr&gt;
  &lt;th&gt;Configurations&lt;/th&gt;
  &lt;th&gt;Dual 1.8GHz&lt;/th&gt;
  &lt;th&gt;Dual 2GHz&lt;/th&gt;
  &lt;th&gt;Dual 2.5GHz&lt;/th&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>and then I wrote the following:</p>
  
  <pre><code> &lt;script type="text/javascript"&gt;
  
  $('#mytable tr').hover(
    function () {
      $(this).css("background","yellow");
    }, 
    function () { 
      $(this).css("background","");
    }
  
  );
  
  &lt;/script&gt;
  </code></pre>
  
  <p>When I hover over the table row, it becomes yellow in Firefox, but in IE it becomes white! Any ideas?</p>
