Hello Shane, I think that you're right about the persistent to non-persistent changes and vice-versa. I will try to identify the object that does this.
What do you mean by removing add-ons? You mean products? And if I remove my third party products and make the objects which subclass the ATFolder broken then I will not get the necessary upgrades specific to folders right? Thanks for your input, Alex.
