scrolling at edges is confusing/poor

when I select a group of nodes and move them to
the edge of a network window, the window starts to scroll (which is good), but the nodes scroll faster.
I think the nodes should stay in the same location relative to my pointer while the window scrolls. Otherwise, I quickly lose the originally selected nodes
and have to search around for them.
