OK i test this, and i think do what is supposed have to do block all mouse events generated by touchscreen globally.
Im trying to find a way the cursor of mouse not is moved to position where I perform the touch and remain in the position indicated by the mouse. If have some idea, please i really appreciate.
For sure this code work also in windows 10

@SaveTheHuman5 Hello, did you find a way to stop the mouse moving? I am trying to do the same thing. Thanks
