Summary: screenblank problem

Thanks for the numerous responses I received to my problem with runaway
screenblank processes.

All the responses speculated that one or more users had "screenblank" in their
.login or .cshrc files and a new copy was started at each login. The
recommendation was to change the mode on /usr/bin/screenblank so that it
can only be executed by root.

It was agreed that the only time to run screenblank is once, at boot time,
in the /etc/rc.local file.

I later found a hidden invocation of screenblank in a hourly cron job which
was created by a former systems administrator here ... I assume his intent
was to kill and restart it every hour for some reason but he only got
halfway there ... :-)

Thanks again to all who replied...
