After upgrading to 10.5, I have noticed some strange behavior with SpamSieve’s icon. Now, when I receive an email, the number indicator in the Dock will be the same for both Mail and SpamSieve.

Switching to Mail is a signal that you’re reading the new messages, so SpamSieve resets the count of new messages.
