Why do my Nisus files open in TextEdit?

[dave]

By default all RTF files on your Mac may open in TextEdit. This includes files saved by Nisus Writer, as RTF is our native file format. However this behavior can be changed by following these steps:

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

4. Click the "Change All" button.
5. An alert appears asking if you want to continue; confirm the change.

Henceforth, all RTF files will now be opened by Nisus Writer.
