Inline Frame - IE vs Firefox Login problem

Kirupians:
Ok, Here is the problem:
There is an inline frame built into the “login” page.
The user logs in INSIDE this iframe.
When using Firefox, you can log in fine.

Using IE, you can’t… It redirects the user attempting to log-in back to the original page.

What in the heck is goin on here!?
