Very, very annoying for me also. I also installed Ad Blocker thinking it would help. NOT. The only thing Ad Blocker did was to keep the advertisement from running. The "skeleton" of the ad still remains and I still have to "X" it to remove it as it locks up the back arrow on the header bar. AAAARRRRG! I have been running SPYBOT on my PC a couple of times a day to get rid of those lurking files. I don't want that junk on my PC.
