Comments+ Comments Posting to Wrong Posts

Hello,

Our blog comments are posting to the wrong posts when your Comments+ plugin is active.

Does this have anything to do with Permalink support?
We have permalinks setup as:
http://showiteer.com/%category%/%postname%/

If I deactivate the Comments + plugin and use the built in comment option then the comments appear on the correct posts.

Any help would be great!
Thanks!
