Captcha problem

Hello,

I put a captcha in a form but it does not appear on chrome, mozilla, it appears on Opera.
In addition I just found that when an error is detected in a field, access to this field is keying which requires updating the page to renew the entry, how to remedy this problem?

In advance thank you for your answer
