Hi, The dombes Abbey librarian had problems with biblio deletion. After some investigations, DELETION IS BUGGED. under certain circumstances, it will delete another biblio, not the one you want to delete. Under certain circumstances, it works fine. I won't explain when it works, and when not. I just say : DON'T DELETE BIBLIOS before 2.0.0RC4 that will fix it. -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
