This should help identify the problem with the cursor:
1. Symptom: Cursor snaps back to the top left hand corner of the screen.
   Problem: WineX supplies relative information.  The game thinks it is 
            receiving absolute information.
2. Symptom: Cursor gets stuck at the bottom right corner of the screen.
   Problem: WineX supplies absolute information.  The game thinks it is 
            receiving relative information.  
3. Symptom: Cursor snaps to the center of the screen.
   Problem: This is a warping problem.  The X server draws the cursor but
            WineX believes the game is drawing the cursor.
 
The first 2 problems are IMO a result of a misinterpretation of the dinput
specs (the dinput debugging is most valuable).  The third is purely a 
WineX problem.
