As far as I have been able to determine, Poser works as long as you do precisley so and so and only this never that and in this sequence not that, never make mistakes and for heavens sake don't save and reload the file. For the cloth room for instance the program messes the file up so badly that eventually you can not do any thing. If you delete the cloth, reload the prop and then set all the setings to what you wanted and learned during you experimentation and all the rest of the animation is done, it works fine. Rather sad if you ask me.
