Ok, weird. I was sure I was able to set IK off in Poser 5, but notice I can't in Poser 6. I've taken to using Wardrobe Wizard to zero my figures and automatically hit "turn off IK" as it's part of the WW process, so that's probably why I haven't noticed.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
