No I hadn't touched the clothing magnets at all.  What I'm seeing is the skin of the model appears to be sort of peeling off the mesh and stretched around the scene, sort of like in 3ds Max when I tried to rig V3 to Biped and missed some parts.  The thing is, it would move around when no animation was running, it just didn't make any sense.

I have a hunch that it may have been the particular clothes, they are freebies off this site and they auto-parent themselves to the body (which is annoying if you don't want that, and I don't, I need to go cut that out of the files).  I need to experiment more with just plain OBJ imports maybe, it's kind of inconsistent - the same clothing item will work once and freak out this way the next time.

I don't see how it could be the figure, she's not being clothified, she's just animating around the scene.  If it's a problem that only manifiests itself with V4, that still does not mean the problem does not lie with Poser.
