Problems continue. What's going on?

Sadly, my attempts to place a sphere along the gaze vector are still not behaving as expected. None of the parenting functions work, and viz.setRefrenceFrame is producing unpredictable results. ...

import vizshape
r = vizshape.addSphere(0.05, color = viz.RED)
r.setReferenceFrame(viz.RF_VIEW)
r.setPosition([0,0,1])

one more thing...

In my original post, I forgot to say that I also made the stereo display the primary monitor. This does not fix the problem, but is essential for stereo rendering.
