With my SideWinder X5, the pointer goes mental in game causing my avatar to look at the floor, as if I was always dragging down on the mouse. With my Habu, this doesn't happen - and oddly if I unplug the Habu without closing the game and plug in the X5, the game responds perfectly. This is the reason I've tentatively labelled this Bronze, as I'm not sure how widespread the mouse input problem will be. If you try this game, please consider letting us know which mice you have, which version of the game you've patched to and how it fared!
Just to note, the mice have issues under the native version as well, the SideWinder plays up in the native Linux client, too.
Microsoft SideWinder X5 : Avatar looks at the floor and spins, until another mouse is plugged in.
Microsoft Habu : Works perfectly.
