I'm starting to understand how frustrating it must be to be a moderator in this forum.

Thanks so much for your help on this. I did search the forum for "duplicate post titles", but did not find any of the four links you included in your reply. I've applied and tested BUGFIX 367-01 (CSS); BUGFIX 367-02 (Duplicate blog titles); and BUGFIX 367-03 (Widgets) in our development area and they resolved the problem with duplicate titles.
