Files "hidden" and not saving in correct format
After the latest update, when I download a file (or export from an application), it is not visible in File Explorer. The only way i can view the file, is to search for it (in EasyFind), select "reveal in Finder", and then it will appear. Plus, when I download a file, the status remains temporary, so I have to add the extension ie. PDF or ZIP to complete the rendering process.
