Whoops, my bad I re-read your instructions and see that it was the buttocks bones your talking about not the thigh.

Yes I see the problem now. and it appears in the new figures as well, apparently Poser reads the right side is read as a minus and the left is read as a plus. Is this what you see and are talking about? It also appears in every figure I've checked with a buttocks set. Is this what you are getting too?
again sorry for the first pics and mistake and thanks for helping me understand soething I hadn;t noticed before now.
