Glitch with Comments

I don't know why this blog gives people so much trouble leaving a comment.  I can't even leave a comment on my own posts any more.  It makes me sign in over and over and over.  I haven't located the setting that is causing the problem, if it is a setting.  However, I did discover that I could sign in as "annonymous" and leave a comment that way.  So if anyone out there would like to leave a comment on a post and can't do it - try doing it under "annonymous" and just leave your name at the end of the comment.  I'll keep trying to get it straightened out.  My other blog works just fine.
