Thanks for the tip! Changing the parent to Ground did work, but I wound up having to key frame and adjust in each frame anyway because of the other problems that kept occuring (the hip started moving on its own!). I guess the idea of "tweening" in Poser is something that either they need to explain a lot better, or needs better implementation. For example, I had the "creature" standing still, and simply wanted to make it blink by closing and opeing the right eye. It is hard to fathom why Poser decided that an eye movement should cause the body to move along the X and Y axis, and add further movemnt to the hip! I had to go into the graph and eliminate these movements. Maybe there is something wrong with my model. It must have something to do with the complex relationship of all the IK chains. My feeling is becoming that Poser was designed as a bare bones program, with the idea that one would purchase models and movements from other sources where these things have been developed, and that being able to do it on your own is possible, but a difficult experience. Perhaps I am too disappointed, or expect too much from the program? Anyway, I have done the animation, and that's the point. The fact that it took three days is idiotic, that's all. Anyway, thanks for your tip and suggestions!
