Google shell/banner in Safari
When I search Google from within Safari, and then click a search result link, about half the time I get to the result page but with a grey banner across the top of the page. The banner has an X, but when clicked it doesn't remove the banner, it takes me back to the Google search results.
What is this, why it is there, and most importantly, how do I get rid of it?
