I am having an issue where I cannot set a file extension that I custom-specified in Code Writer to have Code Writer as the default program. I set the extension .ini to be a Code Writer file extension under the Text category but in the Windows Set File Associations panel I cannot change .ini to open with Code Writer. The app does not show up in the list of applicable programs. However, with .java files, Code Writer is an option probably since .java files are natively supported by Code Writer. My suggestion is that any custom file extension added in Code Writer should make the app available in the Windows Set File Associations panel along with the natively-supported file types.
