Yes, I agree with Nghayward. Unless you need Poser 5 for texture and character creation, there is really no reason to have both version 5 and 6 on your computer. Version 6 is so much better in the cloth room and with lights, plus it has some extra nifty nodes in the material room.

"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
