Unfortunately, after a few months, the problems with our 3Dconnexion peripherals return. The problem starts with preview 3.1.10, until 9 everything worked fine. The 10.7.4 drivers do not solve the problem. If you use 2 monitors like me the current solution is to activate the sync between SketchUp and Enscape and navigate in SketchUp. Several times, however, you have to (or out of habit) to move to the Enscape window and the block in SketchUp occurs. I solved it by putting the 2 icons "stop 3dxware" and "start 3dxware" in the taskbar to be able to navigate again in SketchUp. When it freezes you go back to SketchUp, click on 3dxware stop and after about 10 seconds click on 3dxware start and it starts working again. This disturbs enough but in the meantime it works, we hope for a quick solution. This is my experience with 3Dconn Enterprise, 10.7.4 drivers, nvidia 471.41 studio drivers optimized for Enscape 3.1, SketchUp pro 2021.1.1.
