title: jQuery bug? .appendTo() not working in IE7
body: <p>I am trying to create an option transfer plugin for jQuery.</p>
  
  <p>I have the basic functionality working in opera, firefox, chrome &amp; safari but IE7 is failing to co-operate.</p>
  
  <p>The transfer functions in IE7 appear to operate very sporadically and incomprehensibly. </p>
  
  <p>I have created <a href="http://jsbin.com/opome3" rel="nofollow noreferrer">an example page to illustrate my problem</a>.</p>
  
  <p>Can anyone see where I am going wrong?</p>
  
  <p>Thanks, </p>
