When updating to unity 2018.1.0.f2 and playmaker 1.9.0.f5 I noticed that whenever I scroll the mouse wheel, even with the mouse on top of the state view, it always scrolls the graphview instead. It seems to work correctly on the preferences view.
I've looked into the settings to see if it was a new default but cant find anything. Besides, sometimes it works correctly but 90% of the time it doesn't. It's a bit maddening trying to work like this.
Is this a known issue?
