Expect script not working

Hi all. I have an expect script that I'm using to log into another system and execute some commands. I'm using rlogin, and that part is working fine. The problem is when I log into this other computer there's an application that runs automatically, and it executes some commands but doesn't echo them to the screen. However, having expect running seems to be causing some of these commands to be echoed to the screen, which is totally screwing things up. Any ideas for me? Thanks.
