yeah, that is what I'm thinking too, he might have assigned them to Center button and not the CENTER HOLD button.
Maybe he can try seeing what the center button is set to and make it default.
My center button didn't change and it works as normal. And CENTER HOLD works for me PERFECTLY. It could be bug but it is hard for me to understand 1/2 of what he says. Is english a second language for him? If so, he is doing great because I have not learned how to write or read another language yet.
