After I installed the new Studio, it linked itself to the old 2.x project
files. So if I clicked-on an old 2.x project, Studio will open it and
convert it. It would have been best to create a new extension for Studio
files so the old 2.x projects are opened by the old 2.x program. I think
this is going to cause a lot of issues with older users. They will need to
know to only open files from within the 2.x program.
