I tried the widgets for sliding brightness and soundvolume on my MBP 16". But the sliders don't slide; I can not swipe on the slides to change te level. I have to tap on bar to move the slider (tap right or left from the button, it and then the button moves brightness goes up or down). I this normal? I don't think so...
maybe you have configured a single finger gesture separately from the sliders? They override all other single finger slides.
No, I disabled the gesture (single and double); I deleted them even. No effect.
Weird in general the sliders should work fine, maybe check whether they work in a fresh preset. (But I can only think of single finger swipe gestures that could cause issues here)
Don't know what happened. Tried again and now they slide. Problem solved. Thanks.
