I have actually commented out some code that caused the mouse to go out 
of sync. I do not see any ill side effects at this time as it was 
doubleclicking before I commented out the code.

----Line 487-491-----  /dlls/dinput/mouse/main.c

  /* if (changed) {
  if (This->need_warp != WARP_NEEDED && This->need_warp != WARP_STARTED) {
  This->need_warp = WARP_NEEDED;
  }
  }*/

That prevents the mouse from going out of sync as far as I can see 
without side affects. Now the problem is to deal with the double 
clicking cause everything seems to work fine now :D other than that.

I have also used 2 of your patches.
