Hi 3image, I'll need something less vague than that in order to do something to improve the space mouse support. As far as I can tell it's working fine for me over here.

I added some settings in the Sep-10-2020 v4 beta for some user requests:

3DConnexion updates:
- Updated 3dx default speed on Windows. On Windows 3dx translation and rotation speed was too fast, implement same default speed as Mac.
- Add "Reverse roll" setting in Options dialog under Options > View > Rotate/Pan/Zoom options > 3DConnexion options. Requested by Fred in the forum here:

- Also added individual settings for reversing twist or tilt in moi.ini, under:
[3Dconnexion]
<...>
ReverseTwist=y
ReverseTilt=y
