I have a div which contains a list of elements. Each element can  
receive other draggable elements. The div is scrollable to accomodate  
longer lists as I want a footer below the div to remain visible at all  
times.

When scrolling is not enabled (short lists), the drag and drop works  
fine. Once scrolling is enabled though (longer lists) I find that I  
have to drag elements to what would appear to be the absolute  
coordinates of the target “receiving” element - that is, its position  
if scrolling were not enabled.

Help appreciated.

After some more searching and testing, I have found a solution.  
Setting “includeScrollOffsets” to true in prototype.js fixes the  
problem.

Still, I would be grateful for any other thoughts on this. I’d rather  
not change prototype.js directly if possible.
