I recently noticed that google.com shows a red circle in the address bar (where sites can put a mini logo) and it also shows up on the tab. This is only on the google homepage or results page. It does not show up on other services (google answers, froogle, etc.).
Can anyone tell me what this is? I have tried to find out if this is supposed to be there, or why it is there with no luck. I did recently upgrade to IE 7 (beta or RC whatever they are on as of a few weeks ago).
