I am writing an app that uses external resources (actually runs with the resource file open). Once in a while (phase of moon; etc), the data goes off to MacsBug. I locked down the handle to the resource I want to write to the file, so on. BUT should I be setting something like "SETRESATTRIBPLEASEDONTLOOSEMYDATAAGAIN" bits or something?
