I would suggest you still check the TMG logs. It is likely intercepting the async callbacks. These firewalls that do inspection are a royal PITA.
If you turn on SSL you can usually bypass most issues as well because then the firewall can't look at the content. Nearly all websites are going SSL anyway and things like TMG will become less usable for their original design purpose.
