The largest problem is that there are times in which when the page doesn't load properly, instead of it being a LARGE page like with the last 2 times, the buttons will instead not work. For instance, as you know, the tab that you're looking at will be a bit grayed out to let you know what tab you're looking at, but when it doesn't work, the tab never goes gray and clicking any of the other tabs won't fix it. Other than that problem, I just personally find the style to be a bit... Well, visually unappealing.
