same issue think it was 1.3.22 or 1.3.23 i forget witch worked fine. but 1.3.24 and 1.3.25 both have mouse bug for games. I need to reinstall the wine prefix for 1.3.25 yet to see if this will fix it. also there is a dinput.dll that would fix this. So i heard, and would need to read thru google to find it. Best to use the wine ver. that works for what your need. Not always the newest "Dev/Beta" release. Hope we can get a some stable mouse in fullscreen apps/games soon. Has part to do with linux mouse mouse position thingy a program outside winehq's control.
