Some buttons on a keyboard do not work when play Street FIghter on PC. For example, in Tutorila Mode, page 5/10 can not go back to 4/10 by using "Pause" button on a keyboard; the default setting of this game for going backward is "Pause" button. Please note, however, that if we set other button(s), rather than "Pause," for going backward, the button works properly.
