I''ve found that when I have AutoScrolling set to ScrollBars.Both so that dragging an item around in a tree view will cause scrolling to happen, as it scrolls the _DragItem event gets called again and again for the same item. The problem is that when the drop happens and _DragDrop gets called it process the same item multiple times. How can I prevent this?

In addition, what seems to be happening is that... in the _DragItem I call DoDragDrop. But the actual _DragDrop doesn''t happen until I''m done dragging around, at which point it calls _DragDrop once for each time that _DragItem was called. So I''m confused as to why _DragItem is called whenever I cause the scrollbars to move because of my dragging.
