I already searched for other topics mentioning the same problem, but nothing helps. Hopefully someone can help me out. After a clean install of windows and getting a new (wireless) mouse I reinstalled D2 with Median XL. Everything works well, except the scroll wheel. I can't bind it to previous/next skill. This is a bummer since I play that way for at least 10 years now. In vanilla D2 I can bind my scroll wheel to prev/next skill, but it won't carry over those settings to MXL. Prior to the clean install, my scroll wheel still worked, so I don't know why it stopped working. When I try to bind it I do get the sound of binding it, but nothing happens. I tried everything like sevice packs etc. Unfortunately the MXL launcher only has service packs that go as far back as Windows 8 so perhaps thats the problem. Is there anyone out there who can help me out? Because I really can't play the game without my scroll wheel. Thank you in advance!
