ClassAct was already installed on my system. What happened to “CAPrefs” and the “ClassAct” prefs editor?
They are replaced with dummy files by the OS 3.5 installer and are no longer needed. OS 3.5’s “ReAction” is the successor of ClassAct, and the prefs are initialized via the normal “IPrefs” command that is in your S-Sanyway. You can safely remove the “CAPrefs” command from your S-S or U-S and delete the “ClassAct” prefs editor.
