Basic though it may be, is AppFileCreator really the creator ID
that your app has been linked with? It's easy to forget to change
the creator ID of an app if you use codewarrior and start w/
the starter project...
Get ZarfCatalog and filter on the creator ID you are using,
make sure both app & database are there. Then delete the
app (using the standard Palm launcher, not Z'Catalog) then
check again. If the database is still there but the app is gone,
then we've got a real mystery...
