Still happening today. But, again, it's only by the Virgin Atlantic advert with the diagram of a plane. When another banner advert is up there, it doesn't happen. The only two I've ever had trouble with are this one and the Chase credit card one. The Chase one combined the comments extending to the right side of the window with the Chase right margin advert staying on top of it. The Virgin banner advert just stays on top of the drop down menus.
