    {

        Display_Filling_Constant(&CONF[0],DISPLAY_1,5);

        Display_Filling_Constant(&MENU[0],DISPLAY_2,5);

        Display_Filling_Constant(&BLANK[0],DISPLAY_3,6);

        Display_Show();

        while(KeypadStatus != Button_NOPRESSED );

        delay(1000);

        Menu_Edit();

    }

Hi, It could be the delay(1000) which avoid testing the button during one second. Try without delay or small tempo...
