ok I'll try setting Search to Deep. I can (and did do) change the path manually and it worked fine. I used to make a noise about vendors putting their named folders in Libraries, totally prodding my OCD reflex. Then some nice person suddenly began using a new very sensibly named folder in Libraries.... 'Morphs'. And moving ALL those "vanity" folders into that one soothed my OCD issue. And Poser Pro would automatically change the path IF it initiated the search for missing files. It did not initiate a search at all. It just did not complete the character morph. I adjusted it manually then saved the .pz2 file and all is well.
More news later.
