Why cannot I not assign the right mouse button function to another key? I use many difference CAD type programs that all seem to use different mouse buttons to rotate models. Past logitech software would allow remapping any key, or at least duplicating a key. For example, I have mapped the thumb button to the middle mouse button since Creo uses that to rotate the model. My printing software uses the right mouse button to rotate. I want to duplicate the right mouse button to the thumb button to eliminate confusion.
