I use a vintage 3DConnexion Spaceball 5000 USB model with the legacy drivers on my Windows 7x64 machine and all zoom, pan and rotate functions work well until I turn the model over, then some functions are reversed. None of the buttons seem to work. Using Chitubox V1.6.3.
I also have a current top-of-the-line 3DConnexion SpaceMouse Enterprise running current drivers on Windows 10 where it will only zoom out. Using Chitubox V1.6.5.1.
