Haven’t checked, but suspect earlier versions of FB5 used the deprecated FindFolder function to get special directories. In FB 5.7.8+, FD_SpecialDirectoryXxxx ends up calling a function that maps the old directory constants to NSXxxx constants. Trouble is, there is no NSXxxx equivalent of kPreferencesFolderType. Two ways around it: Either use CFPrefs (NSUserDefaults) or build the path to the user preferences folder.
