use firebug to put a margin-top:15% on the draggable element

drag the element, the offset will be wrong, it jumps around when you click/drop it

putting margin-top:0 in the ui-draggable-dragging class fixes the dragging bit, but it still jumps when you drop it

there is no ui-draggable-dragged class

am i doing something wrong or is this a bug.
