Hi Keith, I also had this problem. I assume you are only on "your Wiki Tree or pedigree view" which displays your ancestors.
My solution was to click on the "ancestor" tab at the bottom of the screen. This will list "your ancestors" with links. Unfortunately when you click on Mom or Dad, gm/gp, etc., it only shows "their ancestors".
I have not found anyway to scroll the pedigree chart (left/right). If you find something like this, let me know. Maybe someone else will know that answer.
