Barb,

Are you creating object references in any of the treeview code that is not correctly releasing them? You might want to get the objref tool from my website and see if it can detect any dangling object references. It's also possible that FOR EACH iterators are creating internal object references that you can't do anything about. If that's the case then you can iterate over the collection using an indexed collection reference.
