IFrame Error

Hello, I'm experiancing some probleming using the IFrame mode.

I get the error:
Service can only be accessed after a Facebook session is established.

I'm not really sure what is happening, obviously the session object is null, but as far as I can tell all of the parameters are getting passed into my application from FaceBook.
I'm not really sure how to reproduce it, if I have the application setup on my developer profile it runs fine. I'm running into problems with new users adding the application. So with a test account, I browse to my url (i.e. http://apps.facebook.com/appname/ ) and isn't of the application redirecting me to the add page, it bombs with the above error.
Is anyone else having this problem?

My fault, I had the EnableExternalBrowsing="true" set, once I changed this all was fine.
