Summary: Mouse "escapes" game window
           Product: Wine
           Version: CVS
          Platform: PC
               URL: http://appdb.winehq.org/appview.php?iAppId=241
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: wine-x11driver

In the menu and game itself Wine allows mouse to "escape" the game window. In
turn Wine looses track of the mouse and character freezes in the game. Forcing
game to reinitialize by changing screen resolution or toggling
windowed/full-screen mode "cures" the problem.

This happens because game attempts to set exclusive coop mode but fails (bug
6960). And instead ending up using background cooperative mode with dinput,
which should not touch position of existing mouse pointer. However Wine has no
means of tracking mouse if it leaves Wine windows.
