I just had the same problem and here is my fix. I found that it only did this when I had the theme changed. In my case it is the blue-mist.1.5.zip theme. I am using WordPress version 2.6.2, so I am sure the theme was old. Anyway I got into design/theme editor and clicked on the comments template and simple pasted in the comments template from the comment template from WordPress’ default theme. Here is my WordPress blog so far. I just installed it a few hours ago: http://www.greatmemories.info/wordpress
