Hmm, apparently it's the mouse driver. It's not just the camera controls that give me trouble, but also the parameter dials. The good news is that I seem to be able to steer everything by typing in the parameters.

I'll see if I can find something about that mouse problem. But I'll definitely go buy the setup tools now. It sucks to do rigging in Poser, and also I want to make JCMs modeled on the posed figure.
