Nope, nothing. No updates, and even turned off my ad blocker to see if that was the culprit. No go. I honestly think it's in the design.

I can tell you that 90% of the time when I've had a page blow out its borders on one of my or my clients' sites, it's been the because the header or footer banner was modified. The person doing the modification has a bigger monitor, runs a higher res, or just doesn't notice the page getting incrementally wider.

The only thing I see that's been modified on BF lately is the addition of the "donate to Japan" verbiage. Can that be wide enough that it's pushing the "Advertise on BF" link to extend the border? You could try tightening that up by just dropping the two "a"s and the extra trailing spaces. That'd net 4 character spaces and at that font size, that's about the distance we're talking about.
