I've had trouble lately with an ad that shows up in the top band of search results. When I hover over a program title, part of the ad remains onscreen and hides part of the text box for the program. The ad that's caused the trouble is for Dave & Buster's 3 Point PowerPlay Sweepstakes. It doesn't happen every time, but often enough to be annoying. I don't think it's happened with other ads.
