EA:

Why not set the model to null (or better, set it to a model with just a
root).  The view (tree) would then reflect the change.

It helps to remember that almost none of the methds for tree nodes are
recursive.  They generally don't see past their own "level".

If you see something that looks like an opinion up there,
it's mine and mine alone.

Mail sent to me from the newsgroups won't bounce but will
be ignored.  If I have time, I'll respond, but you  have
a better chance if you confine your posts to the newsgroups
