However, the second time I tried to run it, I got strange errors. For example, on verifying (from my code) that readpst is installed, I got which readpst no readpst in (/sbin:/usr/sbin:/bin:/usr/bin) The OpenOffice service that was working before suddenly does not respond, and so on. It looks as if one of the machines got messed up, and I only have 1 master and 1 slave. Any advice? Thank you, Mark --001485f20b840a7c7104799b5b1b--
