Keep Your Old Versions of FCP

This post at LIttle Frog in HD is a good description of how to keep more than one version of FCP on your system. The need for doing this has come up with me repeatedly. It is not a bad idea for working with old projects--in case an old project doesn't like being opened in a newer version of FCP than it was created in It also is useful if you have to trade a project with someone who has a different version of FCP than you.
