|After attaching the USB TouchWindow® and installing the driver, the vertical input is reversed (e.g, pressing near the top of the TouchWindow® positions the pointer near the bottom of the screen). Having multiple TouchWindow® drivers on the same computer can cause this issue. Uninstalling all TouchWindow® drivers, deleting the tsharc.sys file and reinstalling the newest TouchWindow® driver will resolve this issue. Consult the remainder of this technical note for additional information.
Complete the following procedures in the order that they are presented.
