When editing the converted text in a normal word processor (for example, to fix spelling mistakes), the joins between text become incorrect.
With Aussie School Fonts Deluxe, the shape of a letter, including the joins, is determined by the surrounding letters. The Helper Program is necessary to decide the appropriate letter shape to use. If text is entered using your normal word processor rather than the Helper Program, the letter shapes displayed may contain incorrect joins.
Type the text using the Helper Program, then copy and paste it into your normal word processor.
