a while ago my player started to jump through the tracks forward, the play and ff buttons seem to be locked, but can be reactivated by pressing tmark, same with the jog dial, but even when i can access the group list after tmark, it does not accept any choice click. the problem occured before and stayed for about a week, then vanished all of a sudden, now after a month it came back for no obvious reason again. someone saw that? firmware update possible? cheers, thilo
