I just DL'd the Viper.
I set up my profiles in game, with an empty DCS profile in the Logitech software (Modes deleted, pinkie set to fallback etc...), joy.cpl MFD Clutch & Latch both unticked...
but when I get into an F16, the pinkie is latched.
Swap to an F15 (in mission [Alt]+[J]), and it's not latched, swap back to F16, = Latched.
Anyone had this issue or know what I'm doing wrong?
SOLVED:
I added Btn6 to [Switches] instead of [Modifiers]
