Sorry, don't know that one. Here's how we use it:

We each have a copy of all source for the project on our local drives.
When I am ready to work on a task, I check out the necessary source. For instance, I'm working on a form right now that has a container in it that comes from a custom class. So I checked out both files for the form and both files for the class library. While I have them checked out, neither of the other 2 developers can check them out, but they still have a local copy. So they can look at the source, they can run the source, but if they change it those changes would be lost.
When I check the source back in, they can then get a new local copy if they choose or they could check it out and make further modifications then.

It works well for keeping us from stepping on each others toes and although I haven't had the need, I know the lead programmer has rolled things back to a previous version a time or two. VSS does have a method for showing the difference between 2 versions of a file, but I doubt that would be of much use on a form or class library since it's held in dbf structured files.
