What needs to be fixed? Do you have an example where this does not 
works? DragImageList is not a control, so it is normal that it stops 
dragging when Target = nil.

DragImageLists is used only for usual drag operations while drag-dock is 
not a usual drag operation. To represent this operation docking frame is 
used and there is no need to mix both representations of drag.
