Just an update on this - a minor annoyance has become a major pain.
This morning no matter how many times I restarted Rhino my 3D Connexion device would not work. I found a comment on the 3D Connexion forum saying that the latest driver (which I’d stupidly installed when prompted) had been withdrawn, which was confirmed when I checked.
So I remove that driver, download and the one I had previously and reinstall it. That still doesn’t work, I keep getting messages from Windows saying its stopped working and no matter how I try I can’t get it set up to work in Rhino as I like. It does work on occasion, but then freezes.
OK, half the morning gone and still not resolved. Next option, download and install the oldest driver I can find. Still isn’t working. Something in that latest driver seems to have fundamentally broken my set up.
Where does the 3D Connexion Rhino plug in comes from? Is it installed as part of Rhino? Reinstalling it is the only other thing I can think to try.
