Comments formatting incorrectly for unlogged users.

Does anyone know why comments from logged in users are spacing correctly, but comments from non-logged in users are not?

When a logged in user types up a comment, <p> tags are wrapped around graphs as the user hits return. However, hitting return as a non-logged-in user just creates a single </br> before starting the next paragraph. This leaves paragpraphs starting on the next line instead of leaving space between.

I’m using Mandigo theme and have MCEComments pluging active. I haven’t seen this specific problem crop up in support for either, but wonder if there’s a conflict between the two of some kind.
