3 monitors "all displays in full screen mode" mouse doesn't work.

[Tyd Ros]

Hello, Workspace app 20.02.05

 

Macbook plus two monitors. Which equals 3 monitors.

 

When you choose  "all displays in full screen mode" with the above setup the mouse stops working.

 

However, if you have a MacBook plus one monitor (Total two monitors) the mouse works.

 

I have read that others can have 3 monitors so that doesn't appear to be a limitation. 

 

Any idea why the mouse wont work?

 

Thanks
