Problem with UTOUCH and a 3.2" TFT

I’m trying to use this TFT on a Arduino Mega 2560 with the Henning UTOUCH library,

Drawing and printing on the TFT works fine but not the touch feature. I try an example somewhat modified with print statements and initialisation to LANDSCAPE mode, see code below. The display does indeed register touches on the display but the coordinates registered makes no sense. They are incorrect or just -1 -1. Don’t see why. The code does display the buttons correctly

// UTouch_ButtonTest (C)2010-2012 Henning Karlsen
// web: http://www.henningkarlsen.com/electronics
//
// This program is a quick demo of how create and use buttons.
//
// This program requires the UTFT library.
//
// It is assumed that the display module is connected to an
// appropriate shield or that you know how to change the pin 
// numbers in the setup.
//

#include <UTFT.h>
#include <UTouch.h>

// Declare which fonts we will be using
extern uint8_t BigFont[];

// Uncomment the next two lines for the Arduino Mega
UTFT        myGLCD(ITDB32S, 38,39,40,41);   // Remember to change the model parameter to suit your display module!
UTouch      myTouch(6,5,4,3,2);

int x, y;
char stCurrent[20]="";
int stCurrentLen=0;
char stLast[20]="";

Just got back from a trip so not seen this before can sympathis spent 3 weeks looking at UTouch ended up rewriting a revised system

Also rewrote the calibration but that still a little off on 3,2 screens had to use big font or bigger than 16 x 16 icons.

If you send me an email address quite happy to let you have the code. its pure C++ not as a so called library for Arduino IDE I use the Xcode / Embeded X option but if you are a capable programmer you should be able to modify.

Don't want to publish it as an Arduino Li=brary not got time to support it at present hence my comment on an email address to send you source..

cheers.
