ie7 sign in interface

This problem probably can probably be fixed pretty easily. When I was using ie7 to sign up for an account, the sign up screen appeared to be something like a fixed background. However, if you type a password that has characters that aren't allowed, an error message comes up which extends off the screen. You can never read the whole message because the background is fixed and stays in the same position as you scroll down.

Hope this helps,
