Thanks for your answer, Wabe. I will probably will organise my stuff in a similar way...particularly keeping new downloads separate from the things that install with the app . I'm not sure what you mean about different versions of Vue... do you keep older versions installed even if you upgrade ? 4 is the earliest I have but it's no longer installed on my HD. If I have understood correctly why do you do that ? And do you know of that version conversion utility I have come across mentions of ?
