Pop "_GUICtrlTreeView_CreateDragImage" out of tree?

[momitty]

_GUICtrlTreeView_CreateDragImage makes a cool little copy of the item i'm dragging around... but I need to find a way to make it drag outside of the TreeView object. Does anybody know how to do this?

I'm just using the code straight out of the CHM help file.
