I can force the user to quit the file's default app before allowing them to encrypt. It's just kind of heavy-handed.
After sleeping on it my choices are to remove the encryption feature or make a big ugly dialog box warning the user if they encrypt a file that's open they will lose their changes. Neither of these approaches are optimum.
And yet either of them are better than the prior idea. Forcing the user to close the PDF and 2 JPGs they have open in Preview so they can use your application to process a PNG (that's open in GraphicConverter) is not only heavy-handed, but doesn't actually provide any benefit to you. Go with the warning; I think users will be able to cope with the fact that changes they save after using your app aren't going to be reflected in your app's output.
