[jQuery] Strange Issue in IE 8 (portlets and sortables)


In strarting a proyect using PHP+Xajax+Jquery.
In traying to use 2 sortable lists into a portlet.
It work fine in FF, Safary and Opera, but not in IE8.
When I try to drag an element form a list, the portlet moves and the
elment gets mad.
Can see an example in http://www.unycorn-systems.net/jquery/dragg.php
Sorry if this a duplicated post, but i cant find solutions or ideas.
Thanks in advance.
