------- Additional Comments From mike@codeweavers.com 2006-06-09 01:21 ------- If you don't know where the good point was, there's not much more to do than go through the dinput patches one by one around the time that you thought it worked, and test them to try find where it did work.
You can't use the regression analysis techniques described in the Wine developer manual unless you have both a good and bad point to start with.
