If the DA is put in the System File (or is used with Suitcase) it will be opened in the system heap and its windows will be contained in the DA Handler's layer. Note that DAs should not make any assumptions at all about characteristics of the DA Handler (i.e. the name, the signature, etc.). Rather, the most a DA should need to know is if it is in the application heap or not, and maybe (but hopefully not) the name of the currently executing application. -Phil Goldman Apple Computer
