Thanks Mike. I have now set an ID for my bundle and it is feeding through
happily.
Now I can set an ID, the docs suggest the format
com.companyDomainName.appName for the directory name in Application Support.
I notice that very few other applications use this format - they tend to use
just the name of the app.
Is there a good reason to follow the suggested naming convention ?
