Dear Guppy,
I guess guys with a lot of experience such as yourself certainly lack the knowledge that the A/P disconnect p/b on the sidestick is also the priority take-over push button. Keeping it held for 40 secs isolates inputs from the other side. I would suggest some more reading and application my friend. Its quite evident you're lacking what is neccessary. I certainly hope this post puts it in simple english for you.
Happy Landings
