I assume you are running the pi as a terminal. at startup the script $home/lib/profile is run.
at the end of the processing in this (not necessarly the end of the file) it does somthing like "exec rio -s -i startup". This starts the window manager and runs the script called startup. I would expect to find a script called startup, probably in $home/bin/rc/startup This is what opens the initial windows on your terminal, if you edit it you can put different windows on the startup screen as you wish. -Steve
