For example, I have 1.2.34 (in special folder, where Wine have own bin/libs/share), and 1.4-rc6 recently installed as current. 1.2.34 I'm using for the game named "Rochard" (cause this is Wine compiled with mouse patch). In 1.4 it cannot recognize mouse axises, regkey= "mouse warp override" doesn't help, but it works with patched Wine.
