Have you by chance installed any new Microsoft software that may be doing some blocking? I'm running Windows XP Beta RC1 and Internet Explorer 6.0.2025 that came with the XP Beta. I find that the banner add that used to show at the top of this screen is now blocked, perhaps because IE doesn't see a valid privacy policy or some other reason. However, I can click on the links on the black bar about 1" down on the screen.
