Hi Ivan, thanks for sending the settings. I was able to reproduce undo/redo by space mouse buttons not working in MoI v4 but working ok in v3 and I tracked it down to a bug that was causing MoI to not recognize the Ctrl key properly in this case. I've got it fixed up now for the next v4 beta.

no, no, Thank YOU! :)
look forward to the next release

Hello Michael,
A further tweak…maybe? The 3DX driver must be ON before MoI4 is ON.
Otherwise the Spacemouse does not work.
With V3 the 3DX driver can be turned on after MoI is running and the controls work.

Hi Ivan, that is intentional behavior, it is recommend by 3DConnexion to avoid a potentially long initialization when no 3DX driver is present at all as described here: https://www.3dconnexion.com/forum/viewtopic.php?t=2814

If you are going to be using the Spacemouse, can't you have it set to run at machine startup and always have it running?

thank you
