I've done forum searches and looked in the Agendus documentation but still don't understand how birthdays work.

I just upgraded from v7 of Agendus Pro to v9 on my Treo 600. Since there is now birthday support I deleted all my birthday annual events, then updated Outlook's birthday field for each contact - but after synching I see that Agendus' birthday field wasn't filled in.

Does anyone know how the birthday support is supposed to work? Can I tell Agendus to synch its field with the one in Outlook?
