terminal shutdown

[Dan Richert]

i wrote a script that accesses files at random from the locatedb
database. it then prints a random line from the file it's accessed to
the terminal screen. this runs continuously and at times makes the
terminal behave strangely (chaning font colors, output writing over
itself on the screen, etc) -- i like this strange behavior, but the
behavior i don't like is when the terminal window closes on its own. i
suspect that the script isn't crashing, but that characters are being
displayed that interrupt terminal somehow. i'm on mas os x. any help
on this would be greatly greatly appreicated.

thanks,
dan
