My "Not Junk" button is missing
I bought my Macbook Pro a few days before upgrading to Mountain Lion so I don't know if this is an old problem. I've been satisfied with the Mail app with one exception. When mail shows up in a spam folder (using Gmail) incorectly, I can't figure out how to mark it as "not junk". Accordng to mail help there should be a thumbs up icon available to do this, but I've tried customizing the toolbar and the icon isn't there, and it doesn't appear as a menu option.
Any suggestions short of reading my email in a browser? I use several email addresses so thats a big hassle.
