To try to make his wrist behave better:- If it is the right hand, do this, else replace "right" by "left". Select the right hand camera. Adjust the view. Select the hand. In the Poser run's menu, select Window, Joint editor. In the Joint Editor window, press the mouse on the white band across the top and select "Twist". That will show like on this image. Use the mouse to drag the red and green ends of the line running along his wrist. That will adjust the blend zone between the hand and the forearm. With the Businessman and my man in overall, the joint zone is likely to be hidden inside the cuff.
