I've just started having the problem of editing track length, I've done this countless times before. But for some reason now it will only let me edit the minutes, not the seconds. if I try to edit seconds only one digit can be changed. For instance the B side of The Police single De Do Do Do, De Da Da Da is timed at 2:34, but if I try to enter the seconds I get 2:03, I've tried a full reinstall.
