The Default Extension (specified in the File tab of configuration properties) was intentionally emptied in the newer versions. When you save a file, in the Save As dialog box, make sure to selecdt “Text (*.txt)” in the Save As Type drop-down list, OR enter “txt” in the Default Extension text box in the File tab of Text configuration properties.
