Hi torsten, that's too bad I was hoping that was it.

Unfortunately right now I have no idea what you're running into with that - I have not been able to observe any differences in mouse orbiting behavior while running on Sierra over here, nor heard anything about it from any other users as of yet. Maybe if more people run into it I'll be able to find a common element and narrow down the cause.

Hopefully it's another glitch caused by using X11/Wineskin and will be solved by v4's native Mac build.
