Disabling Mouse flight control

How do I stop my mouse from controlling my flight? I’m using an X55 but if I move my mouse - like using it to scroll through my mobiglas - it controls my ship. I’ve never encountered this prior to trying to fly in 2.0.

I also had a bunch of random commands while trying to fly in there tonight. Self Destruct, Eject, Quantum Drive Initiated among others.

Crazy times.
