Running Diablo 2 with Crossover in Ubuntu 16.04 x64. I've already installed CompizConfig to change the "Move Windows" option from "Alt+Click" to "Super+Click", and so far that's fine. In Diablo 2, I can set the Alt key to Show Items in the options, but it doesn't actually do anything in the game. If I change it to "Z", it works. I feel Ubuntu is blocking it elsewhere that I'm not aware of, but I find it odd that the game picks it up in the options menu.
