[treeview] - bug: vertical line between nodes breaks in large trees


I've been using the TreeView plugin from:
http://jquery.bassistance.de/treeview/demo/large.html
Unfortunately the vertical line between nodes breaks if there are a
large number of child nodes.
Example screen-shot: http://imagebin.ca/view/wNL8Ez.html
Anybody have a fix for this?
cheers,
