Yes, silverfox, I tried reducing the number of generations, changing the box size, overlapping (etc) ....
What I am working on now is trying to clean-up the database. Years ago I downloaded the tree of another cousin who had done extensive research on his branch and (not knowing any better at the time) I ended up with a bunch of duplicates and differences in how the data was entered.
SO ... I have run an Errors Report ... trying to eliminate duplicates and other errors. I keep saving along the way. I am hoping that once I am done,the Charts will work right.
