App Store shows Updates Available but no apps to update
Ever since the App Store app crashed it now always shows one update available, however, when I switch over to the UPDATES section, the only app it shows (CraigShopper, FYI) is already updated.
How do I get rid of this annoying and erroneous message that 1 Update Available?
