The special ability, which the-boys-at-PARC revealed, and seems to have been lost, except in the ETHO-family [and wily] concerns: a problem consists of multiple entities: each of which should be SEEN; but importantly: they must be introduced/added or removed from the total-VIEW one-at-a-time. Not each SINGLE items SHOWN sequentially. It's a pleasure to have V4 running on this "Windows thing which has the monopoly of on-line capability, in my situation". But V4 can't roam the file-space, fixing problems where ever they are found. The patient must be brought to the V4-hospital. But moving the file to the V4 causes a cascade of unintended consequences. And I'll explain how/where aos failed for me too..... == Chris Glur
