Actually, I found a way. It suffices, in the AdvancedSettings, to set CorrectionType=msmouse and then enable ManualCorrection. I’ve set the ManualCorrection resolution to 1280×960 on my tablet, on other tablet this might need to be set differently. I have played with the game for about 5 minutes in this settings, and everything worked almost without problems. Only occasionally I had to reset the mouse pointer.
