Let me just double check all the captchas
-------- update --------
Login / Register captcha 100% working
Spinner captcha 100% working
The only thing you might find is if you spin the spinner and open another browser, the server controlling the spinner will keep running and the client running the spinner animation stops until you are viewing that browser window. The effect is a spinner that on the server has stopped spinning, but a client that shows everything still spinning. This will be fixed very soon, but it is only a visual issue and doesnt affect your earnings in any way.
