Technical issue: Posting anonymous comments

It has come to my attention that the anti-spam captcha system is hiccuping. Others say that if you try to post a comment as "anonymous" the system rejects the first time to fill in the captcha with an error message that says to try again. The second try works. I've just tried it and found that to be the case. I am not nearly knowledgeable about the technology to know why this is happening or to fix it. It looks like many of you figured this out or are not having the problem, given the number of comments. But if you do get the error message, try again.
