Login not working in iframe; adding your own logo in ncfc

Anyone else experiencing this?
When a user enters a valid user/password the system just returns the user to the login page. No errors.
It seems to happen on Mac Safari browsers and also some other older browsers.
I do have the login page in an iframe on my website, so maybe that is part of the problem?
