Thanks to Vin, I've got a work-around for the comments. Now if you leave a comment, click on Nickname, and a new box will open up that will let you add your blog's URL. Still not perfect, but better than the alternative.
If you are using a Blogger blog, PLEASE go to this link and follow the instructions for how to let your commenters link to their blogs when they comment.
