Yep. I'm in the same canoe with no paddles.
I'd love to take "focus assist" off of my brand new computer, but I have not found a work-around yet.
I've tried everything I can do as a user, and the KHGFGIKLHGGKUYG thing keeps turning itself on somehow.
I'm going to try some other ideas soon - I'm beginning to think there is no way to defuse this bomb.
Whoever designed this "focus assist" =NEEDS= to allow a user to permanently disable it.
Any ideas?
