1. The reason why the figure sometimes moves in a circle is AFAIK because the center point is offset. For instance the Daz  Toon Kitty (or is it the toon dog?) rotates around the tip of its tail. Most inconvenient.

2. I can think of ONE scenario where this is actually nice: When you've just saved someting to the palette and have rendered a nice new thumbnail for it. Other than that, it's just one of Poser's annoying quirks.
