Because mouse is stuck inside secondary Windows computer while secondary computer is in progress of shutdown, before logon or locked.

This is same from Multiplicity 3 to 4. I'm currently using 4.05. Both Primary and Secondary are running Windows 11 23H2.

Multiplicity does not shutdown fast enough while Windows shutdown, results mouse stuck on every time I order secondary to shutdown and I have to wait around 10~15 seconds until Multiplicity in Primary decides to return KM to Primary. It's disturbing.

Unchecking checkbox something like [full screen application is running] at [mouse movement based seamless mode transfer (or something like that)] in Settings tab is not a perfect solution. I don't want KM escape from primary to secondary while gaming. 
(Multiplicity do not support change program language or it's so well hidden, I don't know what is the exact term.)

I know Pro can set this hotkey. I do not need any of Pro's features. I only need to escape to primary while secondary is in progress of shutdown. Nothing else. I don't need hotkey to move to secondary.
Somebody may suggest me to get a Pro license. I'd rather quit using Multiplicity and save that for AotS2 hoping it don't crash like AotS1 the eternal crashfest from 1.0 to 3.31 regardless of PC specs, runtime updates, drivers, and Windows updates.
