I spent the week working with Viliv Senior Technicians to resolve the HID Driver issues and reporting back each and everyone of your comments. Something that has become clear is that HID users need to realise that the presence of a HID Driver will in fact alter the touch experience; there are many technical reasons for this but in plain English the difference is based on the new layer of "thinking" being conducted by the driver to help Windows understanding exactly why you are touching and what your intended action is. You must expect a change in sensitivity but by no means should you expect dead spots!
With that in mind...here is the solution from the factory:
Please use the instructions below to enhance the sensitivity and accuracy for S5
- Check the attached “S5 reset.jpg” file
- Reset the Calibration from Tablet PC setting
- Execute S5cal.bat and calibrate 25point
