Strange form showing for logged in users

Hello WPMU,

Logged in users are being shown a strange form on 'ask' pages. Here is an example URL:
http://www.drgreene.com/askdrgreene/baby-bottle-tooth-decay/. If you see the proper form (which looks like this: http://screencast.com/t/Fhvc8cDDn), it is because you are logged out.

Here is what logged in users see: http://screencast.com/t/5CNmoKbD

Any idea what would cause this strange form to appear?

Thanks,
Paul
