Detecting unread mail

[Steve Loft <steve nybbles co uk>]

How do I get Balsa to show me which mailboxes have unread mail in them
at start up?

I've been starting it up regularly during the day and seeing no mail.
Then I get a phone call from someone asking why I haven't replied to
their mail. So I click on the relevant mailbox, and suddenly it turns
blue and tells me I have one unread mail item. Surely I don't have to
click on all my mailboxes every time to see if I have any new mail?
