Scroll the treeview when dragging and dropping

The only information that I can find on scrolling a treeview when dragging and dropping a node is out on microsoft's support online - Article ID: Q177743

http://support.microsoft.com/support.../q177/7/43.asp

The problem that I am having with is solution is that when the mouse button is released over an area other than the treeview area, it continues to scroll. It does not recognize that the mouse button has been released. It also continues to scroll is you drag it off the form, which microsoft applications do not do.

Does anyone have a fix for this or possibly a better solution?
