Hi Toni, What if, instead of using callback, you put a flag in the thread, to mark whether the thread has been DAO initialized or not. This can be done in application code without needing to modify pjlib's code. Have a look at thread local storage API (you can use Windows's or pjlib's). cheers, -benny > If someone (Benny?) would point me to the parts where the threads get created > and terminated, I wouldn't mind writing the code. > > > Greets, Toni
