It does make it a pain when all you want to do is change one thing.
I got around it by making all the nodes be non-leafs on the chance
that even if it was a leaf at the start, it may need to change down
the road.  This didn't seem to have any effect on the ctree at all
which made me wonder what effects declaring a node a leaf or not
should have.  Does it change the bahaviour in some way I haven't
seen yet?

I'm not sure what you mean by the node text.  When I first create the
node
I pass in an array of char* for each of the columns.  So if a ctree has
multiple columns, what is the text I get back from get_node_info?
