In one case will the form be filled out automatically. The program fills out the form for the Tool itself and then only:
- when the "Update registry" option is enabled and
- the entry for the tool does not already exist and
- the "Add this Tool to SONAR" button is clicked.
The Name field and the Menu Text are required but are normally blank.The name field is the name of the registry entry. The menu text is what appears in the SONAR menu. I am guessing you overwrote the Tool Editor Exe Path with the Audacity Exe Path.
Also the default for the program is not to change the registry directly but create .reg files.
You may want to start over.
Make sure "Update Registry" is set to Yes
Delete the Tool Editor entry
Create a new entry for Audacity
Create a new Tool Editor entry (if you want one).
