Gmail's Black Dot, Do you see it too?
On Both Firefox 3 and Safari, on 2 different GMail accounts I see a black/grayish dot on the top left corner of the page.
Google only indexes Google groups talking about the subject as of today July 4th 2008
UPDATE: 1) Yes, I'm in the US. 2) Some people's theories say that it's an iframe to keep track of your history (so you can click back), and they forgot to remove the border.
UPDATE2: As of August 2008, the dot is gone.
