3DConnexion Space Navigator no longer rotates around selection.
I use a 3D mouse: the Space Navigator by 3DConnexion. In Blender 2.64, it no longer worked. I reported this and after much discussion, the problem was solved and it worked fine up to version 2.70. Here's the previous discussion:
In all versions after 2.70, it does not work. I just tested 2.72b and it is still malfunctioning.
It must be that none of the developers use a 3d Mouse, though I don't know why, since they are so useful, especially for modeling and sculpting.
The previous discussion describes in detail how the Space Navigator SHOULD work. I hope someone will again spend some time to make it work that way again. Thanks for your time.
