New World mouse control issue

Hi everyone,

I am hoping someone else might have the same issue as below.

While playing the PC game called New World, when swapping between the two keyboards via hotkeys using Multiplicity it works fine but the mouse mirrors movements on both monitors when the secondary is selected. If I swap back to the primary the mouse no longer mirrors on the other screen and works normally.

Any suggestions would be appreciated, for now the only work around I found is having another mouse on the secondary PC and using that instead of the primary mouse via Multiplicity.

Multiplicity by itself runs great, it's only during the game when the issue happens.
I am also currently running version 3.57, build 00103.kvm pro trial on both computers.
The primary PC is running Windows 11 Pro and the secondary PC is running Windows 10 Pro

Many thanks,
Terry
