I remember that when I first installed MM6 on a previous computer in 1998, I registered it on-line. As soon as the registration was complete, the window flashed up a message that a more advanced file was available and did I want it. I said "Yes," and a file downloaded. However, I checked immediately, and the version number was still v1.0. I have no idea which file it was, nor what the changes were, and obviously the file itself and the computer which held it have both long gone. It may have been an amended script file, but I don't know.
