The different sections provide different information in the top-most windows title bar.
In the mail section, you get (from left to right)
- name of the mail folder that is being viewed
- name of the email account
then you have 2 numbers in brackets: - first on the left: the number of unread messages. The count goes down as you work thru your messages
- finally on the right another number. I always thought it is the total number of all messages in the folder that is being viewed. But no, that is different and shown in the folder Properties.
So what does it count then??
