bonjour , I miss all of you,,,,

voila je plente !!!!!!!!!!!!!!!! CTRL - ALT - SUPP pourtant c'est un code basique, une simple bouton pour faire quitter(closeDevice) mais dés que je met le curseur sur le bouton un message style billGates ""arrêt du processus par windows"",,,,,,,,,,, ce qui me semble étrange que j'ai suivi le meme démarche qu'avec le code de l'exemple sdk irrlicht N°5:userInterface. please help et merci
