Comment reply Problem with Domain Mapping?

Hi –

We are encountering a problem with the comment reply mechanism from within the admin. area on a multi-site installation running domain mapping. I wonder if this problem and a solution has been encountered before?

Problem occurs when you go to reply to a comment in admin — a red “-1” appears just below the reply field and the comment reply does not register. Nothing happens except for the red minus 1 appearing.

Any help will be appreciated.
