This is on Windows

When I do a Save As, it defaults to the location used for the previous Save As.

However, if that location no longer exists it uses it's parent, and if that location doesn't exist it uses it's parent . . . but that can end up in a location where the current user doesn't have write permission - e.g. the Users directory. If you try to save in that location Windows will tell you that you can't do that, and offer to do the save to your home directory.
