Just a rhetorical question but, what exactly is your idea of the "proper" way to use Apo?? I'd like to know because I would really like to do it the right way and maybe get it to make better images for me... Could you give a few tips? I've been enjoying Apo since '03 and have apparently missed something fundamental?

BTW - Apo already has a way to work in layers that was built into from the very start - the "Export UPR" function. Just stack 'em up in UF - the capability is already there.
