@Donna, I saw that last month too and reported it in one of those long monthly thread. It then went away. But when I did see it, the Adwords Right Column ads were also on the page (not blank like yours) which means they were more pushed towards the center of the page where the heat map show more eye ball impressions. I think that is what they are testing.
