It was that way, petur, really! The problems were with the stop button and also with the play/pause one. And it happened pressing long or short, and with all kind of files (flac, wav, mp3), it just got stuck. And suddenly all started working when I upgraded to the 12.may build.
Maybe the unit just needed a 'warm-up' before start working properly, who knows...
Oh, and thanks for the great work with Rockbox!!
