My touch screen is not what I had hoped. Sometimes when I press on the screen the cursor jumps to the far right of the screen. Also the alignment is not consistant across the entire screen. Near the top it is very accurate near the bottom it is off 1/8" or more. I have ran the cal. several times and have it about as best as I can get it. It is sure fustrating!

Is there a better touch screen driver?

Thanks
Randall

what os are you using?

Regardless of os, what happens if when you run the cal prog, on the bottom sync touches you were to compensate the 1/8 inch by intentionally touching it off by the opposite 1/8 inch?

yes, I've had the same problems with the cursor jumping around. I thappend when you move it too quickly off the screen generally.
CAlibration can be fixed though. You might wamt to enter manual values to fine tune it.
