Hi Darren, I am facing the same problem. I tried adding "Position.includeScrollOffsets = true;" after "Position.prepare();" in Droppables.fire(), Draggable.updateDrag(), and Draggable.scroll() but still I am facing the same problem. I have a div container with overflow:auto style. I am trying to drag elements from a top container on to bottom div container. When I scroll down the div container and try dropping the elements, they either get dropped at different location (these location also include Droppable.add) or don't get dropped at all. I also tried looking for http://dev.rubyonrails.org/ticket/5174 but could not find the page. Any help will be much appreciated. Thanks!
