Crash programma graphics.h

Ciao, sto facendo un programma che prevede un tastierino numerico fatto con la libreria graphics.h... il problema e' che quando si apre la finestra che che ho creato con initwindow(); viene segnalato che il programma non risponde. chi mi puo dare una mano?? il codice lo trovate qui sotto.
un avvertimento, se qualche bel gentil'uomo decidesse di aiutarmi e provare il codice ricordo che va prima installata la libreria graphics.h e poi creato un progretto non un singolo file sorgente... grazie
