Why do my Nisus documents open in TextEdit?

[dave]

By default the Finder is configured to open RTF files (Nisus Writer's native file format) using TextEdit. However, this behavior can be changed in a few easy steps:

1. In the Finder, select any Nisus Writer RTF file.
2. Choose the menu File > Get Info.
3. In the file information panel, under the "Open with" area, choose Nisus Writer from the list.

4. Click the "Change All" button.
5. Henceforth, all RTF files will now be opened by Nisus Writer.
