Les: Well done! I'm actually kind of glad that it doesn't seem to be geometry-switch-related.

I think the current rigging with the hipHandle as the figure root and parent of the actual hip is very, very useful, and I'd rather drop the 'drop to floor' feature than that (no pun intended). But obviously, it would be good to understand where exactly the problem lies. Maybe renaming hipHandle to hip and using a different name for the actual hip is all that's needed. With Poser one never knows.
