Just to be clear, on a RasPiOS machine I see Wheel top surface away from user, text scrolls down in window wheel top surfacace toward user, text scrolls up in window It's been a while since I last used X on FreeBSD I _have_ observed scroll wheels "going backwards" on a pair of old Dell mice that I use a great deal. Contact cleaner applied to the encoder, which seems to be a mechanical switch, fixes it for extened intervals. That behavior was quite erratic, but debris in an optical encoder might conceivably do something similar, perhaps in a more consistent way. hth, bob prohaska
