Good news! Thanks to Alvin’s drivers I was able to restore the touch screen to its full functionality! To be honest, the drivers you attached won’t work well for me, because something was messed up with the pressure sensitivity: it was as if every tap were a right click of the mouse, and it cannot be changed from the settings in control panel. So I reinstalled the older drivers (the one I had a back-up of) but putting Alvin’s SileadTouch.fw into Windows\System32\Drivers and that solved the misaligned issue!
Can you post the driver files that worked for you please? Other ones posted make my touch screen way off. Thanks.
