I Handle the event of on/off button, or autooff to perform some actualization of variables when the palm goes off. But the problem is that the device execute the same routines when I activate the BackLight with that button. I know there is some diferrent keycodes, hardPowerChr and backLightChr and there is another one for the backlight, (i cannot remember it now) but the palm seems to send me the hardPowerChr both for going off and for toggle the backlight. I need not to do those routines when the backlight is toggled. Any Idea? Thank you very much for you help Ariel Barreiro Movilogic S.A. Buenos Aires Argentina
