I did a quick search, but couldn't find anything. I'm sorry if this has been posted already.
ZD B3 allows you to select a calendar when creating an appointment. However, it seems to always pick the last calendar/user in it's list, while the first calendar/user is my primary.
If I'm in user 1's email, I had assumed that by default, when I click on calendar, I'd be in user 1 calendar. But that's not the case.
