Hello. You are right Alexandre RENOUX(ST Employee). I found the problem. When I touch the touch screen, the function return the true coordinate but at the moment I release the touch, the last coordinate was unvalid (I mean the last coordinate that the function returned is outside of the range. ) so I filtered the unvalide coordinate and the problem solved.

thanks to everyone.
