Well, thread topic says almost everything I think: I can't open the inventory with the scroll wheel, despite it working without any issue in Deponia 1.

Not a terrible bug, but still annoying.

I'm using the German language patch and the game runs on Windows 7.

Silly question, but is it enabled in game's settings?

Of course. It's not only enabled by default, but it's also the first thing I checked. ;)

Sometimes it does not work for me due to a glitch so I just load the game again. But I don't think that's the same with you.

Yeah, I started it a few times now, and it never worked.

Anyway, since I already finished the game now, it's not that important anymore. ;)
