Jquery Draggable and Droppable is not workin in IE 7/8

Hi,

I am facing a problem while dragging and dropping in IE when the Drop list count < 2.

If the List count >=2 i can drag and drop the items.

When I tried to drop an item where the dropping list count < 2 and then I can't access any other Ajax events(Ajax Submit Button) in the page.

Its working fine in Safari.

Please suggest where I am going wrong..

I am using this functionality with Project Wonder framework.

Thanks,

Pavan Jayam.
