screen as a login shell -- problems with scp

[Derek Carter]

Ok so I use screen quite a bit.  I finally got tired of reconnecting to 
my screen sessions every time I logged in. I made the move to screen as 
my login shell.  Now scp doesn't work. Here is and exerpt of what I get:

$ scp /etc/passwd address@hidden:
Must be connected to a terminal.
$

no dice.

I was wondering if anyone else has even tried screen as a login shell, 
let alone seen this problem.
