I just replaced my iMac (system was older version) with a new Mac, Catalina system. I am using LibreOffice 18.104.22.168. I just tried to save a file with the “Save as …” command, and no save window came up. I then tried to export the file with the same result.
Please let me know how to get the file in some format that a person without LibreOffice can use it.
