Sorry if this has been mentioned before. When I'm using my mobile device (Android) for navigating the message board, the Recent Topics window in the top right-hand corner of the screen will disappear. It is there when I first load the page, then disappears after a few ticks.
Obviously this isn't a big deal (I've been dealing with it for, like, ever), but I figured I would throw it out there in case its effecting anybody else. It is convenient to have those links available when you're surfing the MB.
