When I just tried to link Mary (Alley) Lindsay (ID Alley-766) as mother to Mary (Lindsay) Munro (ID Lindsay-3721), it briefly displayed some sort of red error box and then the box disappeared was replaced with the usual message to coordinate with projects on pre-1700 profiles and then a whole bunch of white space. Strange, as I had just linked Mary (Lindsay) Munro's father a few seconds before with no problem. Is the error a bug? There at least seems to be a bug in how it's displaying whatever error I'm tripping.
EDIT: I see what the error message probably was: daughter's birthdate is after mother's death date. But there's still an issue with how it was trying to display the error message, since it vanished a split second after appearing. Maybe it's an issue with my Chrome browser?
