IB_VTree does not use any sophisticated loading tecnique, its basically like
a brute force sorting algortithm. I planned on doing something with it
eventually. To be honest with you, I'm not sure why you would want to load
35k records into a tree anyway. It becomes more or less unuseable for the
user to use anyway. You should consider a more selective query. I will keep
working on it though.

This component actually works. It separates the data from the tree which
makes it easier to to use IBO components

IB_VTree. I really liked VirtualTreeView and would prefer to go back to it,
but I'm just not ready to tackle the issues that I ran into with IB_VTree
(I'm still very new with Delphi5 programming.).
