Summary: Quake Wars mouse wheel scrolls twice instead of once
           Product: Wine
           Version: 0.9.45.
          Platform: PC

        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: wine-directx-dinput

In the Quake Wars demo when you scroll the mouse wheel, it is supposed to move
the voice shortcut selection up or down by one.  In Wine it is scrolling twice
instead (so you can only select 1, 3, 5 etc.).

The normal terminmal output probably isn't useful for this as it doesn't
generate anything when scrolling.  Is there anything I should attach?  I have
set this to dinput as I know the game uses dinput, but this may be wrong.
