It gives me the new version as well, but it seems google is convinced that I am a bot. Getting a regular captcha after clicking the button and I have to say that this is a lot worse of an experience than regular old captchas. Now I have to wait for a few seconds after clicking a button, then still solve a captcha.
I attempted tabbing to the checkbox and pressing spacebar (not moving the mouse at all) and it worked just fine. Impressive. But I guess the tell-all is how secure it is against bots. not how easy it is for humans to get through. For all we know it could just be letting everyone through :P
