Wild guess is that this is because of the 'Already reselected' line above. lsi_reselect() sets s->current, and later when lsi_do_command() is called it gets confused because s->current is already set. But i would need the whole logfile to see why this is going wrong, or even better AmigaOS (which is not free as you already mentioned) Sven
