In the Offline Editor v3.1 on macOS Catalina (10.15.4, german) the scroll functions with the mouse wheel or cursor buttons don't work. So it is not possible to select a fixture in the patch. The input monitoring in preferences of macOS is set.
sstaub you must click and drag - mimicking a finger press and drag. The wheel was disabled due to some issues with scrolling.
Thank you, that is a new behavior.
Good to know, I make in the moment the review of the german manual.
