i am not a robot

I don't know what you "improved", but your system frequently badgers me now as to whether I'm a robot.  So I dutifully hold down the button for 10 seconds to get past it.  But of course your system now wants me to verify it again and again.  I'm running the current version of Firefox (though other browsers fail too), and you've got 56 cookies saved on my Firefox so we know that's working. 

With 56 cookies on my system, you can't store one that says "don't badger me about being a robot" again (and again, and again)?
