Hi Ivan, well that's an improvement at least. Neither MoI v3 nor MoI v4 did any special handling of the 3DX keys for undo or redo, so if it worked in v3 I would guess that the driver is sending a Ctrl+Z keystroke. I don't know why they don't do the same thing for the newer interface as well.

Can you show me how you have the 3Dconnexion driver settings configured so I can set mine up the same way over here to test with?
