Something has gone seriously wrong with IE8 this morning. I turned on my PC (a 64-bit version of Vista Ultimate with SP1). I bring up IE8, and try to go to anything in my Favorites folder, and it is impossible. All links within my Favorites are not links at all. I don't know what they are, but they're not links. I can do a Properties on any of them, and they'll indicate that it is a .URL file, but that's it. I can click on any link in my Favorites until the universe ends, and it does nothing. In addition, all of the icons associated with every link I've got in Favorites is now shown with a plain, blank icon.
Something is very weird and I've no idea how this happened, why it happened, how to reverse it, etc. Help, please!
