I haven't had any reports like that before. Would you mind sending me that PAF file so that I can reproduce the error? If I can reproduce the error, fixing it becomes much easier.
Just a follow-up note . . .
I imported my PAF data from a GEDCOM file. It appears everything is accurate and complete. My earlier concern is still unresolved. I emailed you (Michael Booth) a copy of my PAF5 data to try to recreate this import error. Thanks again for checking into this.
I'm impressed with Personal Historian. This software is exactly what I've been needing for a long time to help write my family history biographies.
