[Qt-interest] help with tslib

Strange problems that I have not seen before. I would suggest trying to
hand write a calibration file and see if you can get the touch screen to
act a little better. It may just be that the calibration isn't working
correctly so it's throwing the touchscreen *completely* off. It would
make sense that the mouse disappears when you touch the screen. My guess
is that the calibration is so off that it moves the cursor to the edge
of the screen once you touch the touchscreen.
I hope the following links help because I have not seen this problem before:
