just updated to SKP 2021 and Enscape is 3.0.2+44009. 3d connexion driver is also up to date, and the computer is rebooted since then.
The 3d mouse wasn't working in SKP, and property window shows Enscape instead of SKP even though Enscape isn't even open yet.
When Enscape is open, the 3d mouse does work in Enscape window. But I cannot figure out how to use the 3d mouse for actual modeling, which is more important use for the 3d mouse, not viewing in enscape window.
