Wow, I would never have thought of doing that to get to a new state. I can't think of the number of times that I have opened an existing document to make alt versions of, but forget to Save As before making those changes so my alt is the version. Hopefully undo buffer allows me to go back to start, Save As, redo back to where I was. Too many times.

I love/hate when I hear about the covoluted ways that users use a computer in the most illogical way that apparently makes perfect logical sense to them. It's like the Stupid Criminals bit on the Tonight Show. All you can think at first hearing is surely nobody is that dumb, but yet, here we are looking at someone being that dumb. One co-worker was often heard saying "I can't fix stupid"
