--- Comment #32 from Stefan Dösinger stefan@codeweavers.com --- I recommend to run the game on Windows and take a screenshot when a mouse pointer that's not working on Wine is shown. If the mouse pointer shows up on the screen, you have a software (i.e., glide / d3d9) rendered cursor. If it does not show up you have a user32 cursor (since you already ruled out overlays). That should limit your search for the problem somewhat.
