I am using the following script:

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script>

    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"  type="text/javascript"></script>

    <script type="text/javascript">

        $(function () {

            $("#sourceTable tr:gt(0)").draggable({

                revert: 'invalid'

            });

        });

    </script>

When I load IE8, the rows do not drag.  Curiously, when I drop the tr and only have this

$("#sourceTable").draggable({

It works

In addition, it is working on IE7

Is there a setting on IE8 I need to be aware of?

I am developing in a MVC 2 solution in VS2010.

Thanks
