I've gone from 2.63a to 2.64a and my spacemouse axes are behaving completely different! I have the latest Beta drivers from 3dConnexion.
I can no longer zoom in ortho mode. While I'm in ortho top/left/right and I navigate the object orbits but the display stays in top/left/right and the grid zooms in and out.
And the biggest annoyance is that it navigating never pivots around the selected object, even if I center!! It's completely unusable.
Has anyone else had problems with this?
