Got an iMac running 10.7.3. I was trying to write an email in Mail and I wanted some text underlined. So I opened up the little font drop down icon and click on the u which underlines the text. But I want to remove the underline so I highlight the text and click the u again... Nothing. Did not remove the underline at all. Tested with Bold and Italic; that all works. But underline is busted. How do I get this to work?
