It can't be privacy, because I used the dynamic tree before I moved; I am on the trusted list for all my close family. To check, I tried to view the Dynamic Tree for ancestor from the 1700s. I failed. It's possible that my inability to see it is because I'm in China, but I deem that unlikely because everything on the page loaded except the tree; were it a Firewall issue, I would have received an error message. I wonder what platform they use to show it; I have Flash and Java, but I may need to download something additional.
