thanks for the reply.
I think everything is up to date. Mac mini 2.8GHz Intel Core i5 running High Sierra 10.13.3
SpaceMouse 3DxMacWare V10.5.1
Rhino version 5.4 (5E407)
The SpaceMouse is actually the wireless version, and I think this is part of the problem. Some times after power up, or after returning from sleep, the only way to make the SpaceMouse work is to disconnect then reconnect the wireless adapter.
Using the SpaceMouse (wireless) and Rhino has always seemed a bit flakey. A problem I had a few times in the past was working in Rhino, then switching focus to the browser and accidentally knocking the SpaceMouse would cause Rhino to just keep zooming out. Eventually I realised unplugging the wireless adapter would stop the constant zoom.
As I said in the original post, the SpaceMouse works fine in its own app, so I assume it’s something to do with the way it interfaces with Rhino.
I think I’ve read in a previous post that not all models are really supported in Rhino, so?!
I’ll try reinstalling drivers and I guess Rhino and see if it helps.
