I had some individuals in my GEDCOM files whose dates of births were the month and day only without a year. FTM 2008 apparently decided to assign a year or something. My great-aunt, for whom I only had a day and month of birth was assigned a year of 4713 BC. I noted most of the others were assigned this year as well.
Gives new meaning to the phrase "old as the hills."
Not to mention my FTM 2008 runs slow on both my older machine at home and my newer machine at work.
