Droppable : The coordinates problem on scrollable div


Hi,
I encountered a problem about the droppable plugin. I wanted to
drag a item into a scrollable div , but the plugin could not re-
calculate the coordinates after the div was scrolled,the coordinates
were same as before scrolling, so that it made the onover /ondrop
could not work properly as well. Anyone knows how to fix it?
