Pro Sites signup form - "No, I'll do this later" is checked, but fields still require

Hi,

Pro Sites signup form - "No, I'll do this later ." is checked, but fields still required and the user registration fails. Is this a configuration issue? I don't recall this happening b4.

BTW, I could not select ProSites plugin when I created this question under IE9. Hmm, I have an image but don't see how to attach it...
