Odd UI issues

Odd UI issues


I am using jquery ui 1.6rc5 on my development server and have an issue
when I try to cancel a sortable in IE only I get an error this.helper.
0 is null or not an object. Since there is a newer final version of
the ui, I decided to switch to it. In doing so, however, my sortable
is no longer able to be dropped on. Here is an overview of my page:
I have 1 Draggable list on the right containing a list of teams and 1
to n number of sortables on the left to be a series of review steps a
document needs to go through. Any ideas?
Here is how I setup my draggable:
    $("ul.droptrue > li").draggable({
        helper:'clone',
        connectToSortable:['.dropCatch'],
        revert: 'invalid',
        opacity: .50,
        placeholder: 'ui-state-highlight',
        update: function(){
            $(".dropCatch > li").css({"width" : "621px"});
        }
    });
and my sortable:
    $("ul.dropCatch").sortable({
        revert: 'invalid',
        connectWith: ['ul'],
        opacity: .50,
        placeholder: 'ui-state-highlight',
        helper: 'clone',
        update: function(e, ui){
            //code removed to save space
        },
        receive: function(e, ui){
            //code removed to save space
        }
    });
