Attached Link: Comparison Animations

I am trying to use Poser to create 3D images for lenticular. In order to do this I need to animate the camera so that it pivots in a small arc around a point. I seem to have stumbled on a bug.

I inserted a ball primitive into my scene and made it invisible and set the Main camera to point at it. I then go to the last frame and use the x dolly to move the camera a small distance to the right.

The problem I am running into is that this works fine in preview mode ( the camera rotates around the ball) however when I render using firefly, poser4 or sketch the camera now rotates around some other point in space way back in my scene (possibly the origin point).

I've put two animated gifs on a page at my site. Note how in the hidden line render the ball is stationary  but in the sketch (and firefly and poser4) render it now moves.

Anybody seen this before, have a clue why and maybe some suggestions?

Thx
