Chicagoboyz Commenting Issues

A frequent commenter complained to me that he had tried to post comments and the comments either didn’t appear or he received a WordPress error message telling him that he had tried to post a duplicate comment. I’ve had similar problems myself once or twice. Is anyone else experiencing such issues? Please let me know if you are. There may be a tech issue, perhaps with our WordPress plugins. In that case it would help if I knew the scope of the problem so that I could find its cause.

Thanks.

UPDATE: The problem appears to be a browser issue.
