Hey, this might be an issue reserved for those using the newest version of Chrome (I've noticed a lot of odd issues, like this accursed new scrollbar) and isn't really a big deal in the grand scheme of things, but the site's fonts are acting up. Essentially, they switch from the serif typeface the site uses for its headers and tabs to a larger version of the sans-serif typeface used for regular text. What's odd is that - in many cases - as soon as you wave the cursor over any of these instances, it'll change back to the original.
This might just be a Chrome bug, but I figured I'd log it if only to check if anyone else is seeing the same thing. Maybe I'm just assuaging a fear that this is all in my head. (Chrome Version 32.0.1700.72 m)
