TreeViewAdv Crash

Populating a tree view with enough nodes to make it scroll, then scrolling to the bottom and removing nodes (so it doesn''t need to scroll anymore) will cause the scroll bar to gray out but not show all the nodes in the tree view. Trying to manipulate the nodes results in a crash. I''m using EnsureVisible on the top most node to get around it for the time being, is there another solution?

I''ve noticed that the EnsureVisible doesn''t always work, and it''s not 100% reproducible when it''ll work and when it won''t. When it doesn''t, however, the tree view does manage to correct itself without crashing if you try to click on something in it when the scrollbar is grayed out.
