does this happen to you as well?

You know when you're trying to comment on a post and you're instructed to "type the characters you see in the picture above" when leaving word verification? Well, many times when I do exactly as I'm told it rejects what I type in (even on my own blog) and proceeds to tell me in angry red letters (with an annoyed-looking exclamation mark first no less), Enter the letters as they are shown in the image. Um, that's what I do the first time, but half the time it doesn't believe me! So now I usually type the non-word very slowly, letter by letter, wondering if either my vision is deteriorating even quicker than I had suspected, or if I'm just going barmy. Well yes, MY bet's on the latter as well, but still! How rude of my own page to not trust my ability to recognize letters! Besides, why should I have to verify anything on my own page? Doesn't it know it's ME who's doing the typing?
