The preference editors are based on OS 3.1 source code, using Topaz 8 as a fixed-font setting. We neither have ReAction at this time, which the OS 3.9 Prefs require, nor the source code of the latter. That’s also why we had to rewrite the editors for ASL and Workbench Preferences from scratch. Font sensitivity will return to the Preferences editors in a later release; don’t worry. Just be reminded: There was little man-power, and so much to do.
