It's a new feature with 2.2. When you load files with a new major release, it has to be converted to the new format (which encodes various new features). We had some cases where people tried to load files with 2.1 and the file was for some reason corrupted. Of course, they had a backup. Or not. So now we do not over- write the original file, but just rename it. Richard
