This has reduced the number of inadvertant 'deselections' of ALT SEL, but it still drops out on movement of the pitch wheel in the final stages of capture. Still a bit of a gotcha, particularly at night. All the other knobs on the APFD panel are back lit EXCEPT the pitch wheel. It's easy to nudge as you reach for selections either side of it.
I have a very easy remedy for this problem when I am flying my Dash-8.
Don't touch the afcs panel when it is in the capturing fase.
