Wait, you just want a list of users that have the file checked out?
I am running VSS 6.0a, and that is the default out of the box: In the right pane of the GUI, in the "User" column, you should see the name(s) of all users who have the file checked out (you may have to expand the column to see all of them).
Is this what you wanted, or did I miss something?
