Pink highlighting in Apple Mail
This a brand-new problem for me, although apparently it has plagued Apple Mail since time immemorial. I how have a pink highlight in my Inbox and Drafts directories when I ham actively in Apple Mail. How do I get rid of it? (I tried a 1917 solution that involved rebooting the Finder. Nada.) Thanks for any help you can give. I'm not a Pink-Email kind of person.
