Draggable has offset when page is scrolled

Draggable has offset when page is scrolled


Hi
I have a page with a (long) list of object on the left and a droppable
on the right.
When the page is not scrolled, I can drag and drop items to the right
normally, but when page is
scrolled if I start dragging an object from left list to the right
area, the helper (moving object) appears with some distance from mouse
cursor, this distance increases with increase in page scroll size;
How can I fix this?
Best Regards
