Comment section not retaining user info

Hi all,

Since upgrading to 1.5 (I’m presently at 1.5.2), the blog will not remember a past commenter’s user info (like, Name, Mail, Website). It all has to be retyped each time, which was unneccessary in the previous version. Is this some weird cookie issue? Improper settings in admin? Ideas?

Thanks.
