Many thanks for your reply.
This is my first day, so be gentle,

I can turn the big pitch wheel, as in your screen shot, my problem is the selector that switches from NAV, HDG,MAN, LOC VOR, GS AUTO, GS MAN.
The + and - symbols show when I nput my mouse over it, I get the "click" sound, but it will not move.

Am I missing something?

Eddie :-?
