Continuing saga of word verification

OK, now this is just too weird. I was going right along, reading blogs in the Quilting for Fun webring, when BOOM...I was hit with the evil red x in a box! So, I just typed in a few letters, and presto, it gave me the word verifcation letters. I typed them in, and it told me I had it wrong and gave me new letters.....I did this three times. And then I had a thought, I typed in the letters that were from the previous attempt - they didn't match the current letters, but heavens to Betsy - they worked. Now how weird is that?
