When I am on the this site (meta), if I move my mouse cursor onto my user name, a drop down box is shown with table of my activity. Also, when new questions show up on the "Questions" page, a clickable link is displayed saying something like "N new questions on this topic".
However, on the main SO site, neither behavior occurs; it's as if the page is "dead".
Is this something I did to myself or is something going on with the SE server? I'm using a Chrome browser on Windows 7, if that matters.
I'm mostly interested fixed the "new questions" behavior if possible, saving me from manually refreshing the page every now and then.
