Mouse wheel sometimes sets volume of layers to zero.
Has possibly something to do with the layer being scrolled off screen / reaching upper or ower end of the list.
Won´t happen with the layer which has the current focus.
Won´t happen when using the scrollbar
… that’s a bug. Position your mouse cursor of the horizontal volume slider of a layer. Now begin to scroll → it sets the slider to zero. Sorry! We have fixed it. Next update.
