Software source

When we buy software here, we like to copy the CDs to the NAS for ease of use and in case the CDs get lost or scratched. This is pretty standard practice. Yesterday I heard an amusing story. One of our developers (and only one) is using an old version of Powerbuilder. When queried, she said that there was a version of Powerbuilder on the NAS, but that was not the version she was using. To make matters worse, she didn't HAVE the source for the version she was using. Apparently it had been corrupted. Her solution? Well, it lives on 2 of her desktops and a laptop. Let's all pray that nothing happens to those machines.
