Internet Explorer problem: Can move objects only once

Internet Explorer problem: Can move objects only once

Hello!

I'm using jQuery with the draggable interface from http://interface.eyecon.ro.

I got a problem with the Internet Explorer (V8, not tested yet with lower versions):

Once I've moved an object, I can't move it anymore. I still can move other objects, but the rule is the same: Only one move is allowed.


Here is the relevant part of the code:

<style type="text/css" media="all">
#myframe {
   position:absolute;
   left:256px;
   top:151px;
   width:700px;
   height:525px;
   background-color:#fff;
   z-index:22;
}
.vDrag {
   cursor:move;
}
#name {
   position:absolute;
   left:0px;
   top:0px;
}
#name2 {
   position:absolute;
   left:0px;
   top:80px;
}
</style>

<script type="text/javascript" src="/js/jquery.js"></script>
<script type="text/javascript" src="/js/interface/iutil.js"></script>
<script type="text/javascript" src="/js/interface/idrag.js"></script>
<script type="text/javascript">
$(document).ready(function() {
   $('.vDrag').Draggable(
         {
            axis:'vertically',
            containment:'parent'
         }
      );   
});
</script>


<div id="tb">
<div id="name" class="vDrag"><img src="image1.png" /></div>
<div id="name2" class="vDrag"><img src="image2.png" /></div>
</div>


But the demo on eyecon.ro works with IE:

Does anybody know what's wrong with my code?
