PoserPose Bugs?

I'm really enjoying PowerPose and am finding it very useful, with one exception.

When you click some of the control points in the PowerPose panel the actor vanishes, and they you typically have to force quit Daz to regain control of anything.  I'm on one of those silly little tinkertoy plaything Mac machines.

To replicate the problem click and drag the control point in the lower right hand corner of the PowerPose panel, body section.  Some of the other control points do this as well.

I'm reading the PowerPose docs and see no mention of this so far, so I'm guessing this is a bug. 

Most of the control points work great, so I'm trying to memorize the Death Star points so I can avoid them.
