After upgrading to Yosemite I notice that if I right-click on the Caffeine icon in the menu bar, the blue background that appears never goes away. The icon's background just stays blue no matter what I do: I can select an option, I can click somewhere else on the screen, it doesn't matter. The blue remains. Doesn't happen with any other menu bar icons. With them, the blue background disappears as it should. Any other Yosemite + Caffeine users out there having this problem? I'm on a mid-2012 13-inch MBP, OS X 10.10.
