I've been having trouble adding people to my tree. I can input the details but when I click save&close, it goes back to the tree view but there is this "wheel" scrolling and it just keeps rolling until I click the back button. When I go back to the tree, that person has been added there several times. I've never had this problem before and now it's happening on my laptop as well as desktop (both in Safari and Firefox). Any ideas what to try?
