Are you sure you want to use system()?  You do know that your app won't be
able to do anything while the command you ran with system() is running,
don't you (this includes redrawing if part of the app gets
obscured).  Maybe you should look at using fork() and exec() to start the
program, along with a SIGCHLD handler to catch its death (at which point
you use wait() to clean it up).
