Does anyone know how to prevent the 737 panel night lighting from auto switching on?,,and also how to extinguish the speedbrake armed indicator on the main panel.-sorry if these issues have been raised before but i did a search and had no success.

I dont know about the lights but did you make sure the brake lever is all the way forward on the throttle ped.

yes i did...i actually tried SHIFT + / and also with the mouse,,but no joy.

You have to find the click spot on the throttle. The standard arm for MSFS doesnt work with the 737. Also try a search from awhile ago you will find some posts on the subject
