Yea, the captcha appears fast now, but it only works for a few claims, then it looks like it get stuck.. I make claim after claim... but they are not going anywhere, not to pending, not anywhere... and after 10-20 claims like that they are all goes to invalid  
I have just made another test, I have made 20 claims and during making those claims no numbers was changed, after some time I see I have 2 more on Validated and 17 more on Invalid. I am sure I havent make any mistake while solving captchas, at least not that much
