MSFX 2020 black/white dialog boxes

First, I think MSFX is a wonderful Flight simulator training tool!

That said, I'm wondering if someone can answer some questions:

1. How do I remove those annoying black/white dialog boxes when I try to adjust an instrument with my mouse? I flew last night, and those didn't pop up when I was in the plane. I understand what the instruments are for, and how to adjust them, and the
boxes just get in the way.

2. Microsoft's keystroke notation has been difficult. For instance, what does "T6" in a box mean? Also, they number the buttons on my Saitek yoke in the game, but the numbering doesn't seem to correspond with anything in the game. Where can I get notation
definitions?

3. The Garmin 430 look alike doesn't accept the final click of the "Enter" button when trying to use the tool for navigation. (It usually is "Direct", enter the 4 digit airport code, then "Enter", "Enter" to activate. Is that a bug?

5. I have 3 monitors, and would like to have one focused on the center view, and the two side monitors one the side views each. Is that possible and how if so?
