Hi George,
  The TreeView actually works differently here than you might expect.
Since it is Model-View-Controller based, the view will never directly
modify the model (in this case, toggling the actual boolean value).
Instead you need to update the model value once you receive the toggled
callback, like so:

public void enabled_toggled (object o, GtkSharp.ToggledArgs args)
{
	Console.WriteLine("toggled {0}", args);

	Gtk.TreeIter iter;
	if (store.GetIterFromString(out iter, args.Path))
	{
		bool val =3D (bool) store.GetValue(iter, 0);
		store.SetValue(iter, 0, !val);
	}
}

  The view will receive a notification of the changed value and update
the check mark accordingly.
