Obviously, this is the first time I've seen the VS diff utility, otherwise I wouldn't be posting so many issues in a row, but I've got one more. This time, it's a bug -- granted, a very, very trivial bug, but a bug nonetheless. When you click the Previous or Next Difference toolbar button and keep your mouse hovered over it, the image disappears. Well, let me qualify that. This only happens when you press the previous button on the second change or the next button on the second to last change (namely, the last click that ultimately disables the button).
