I am running Rhino SR11 64bit, and I’m using a 3Dconnexion 3D mouse. Recently Rhino started displaying a popup with the message “The 3DxWare driver is already running.” on startup. The mouse doesn’t work when this happens.
I’m not 100% sure but I think this started after I installed the latest Rhino service release. I haven’t checked yet if reinstalling the driver might help, just wanted to check if someone else is having this problem or solved it already.
