Click Etc > Play Music. Load mp3, it, s3m, mod, spc file. NO PLAYBACK. 'Play Music' command is checked.
Load mid, there is a playback but 'Play Music' command gets greyed out instead of being checked (not normal). You cannot load another unless tunes are stopped.
***DANG! Two bugs in one thread. Since they were both fixed, too late to split up myself.***
