Yahoo tab at the top of my browser shows I have new mail. When I click on the mail tab, primary mail is listed (as default) but there is no unread mail shown. If I click on the "all" tab I can see unread mail here along with everything in my "primary" listing. Why doesn't unread mail just show up on my primary list like it used to? Alternately, if I could make the "all" list the default setting I would immediately see the unread mail. Why is it when programmers "improve" a program they seem to break more stuff?
