I've been working on my tree for a year and a half in Safari with no problems. However, starting a few weeks ago, the tree no longer responds to my touchscreen. A slight finger swipe to reposition the tree actually moves the tree clear off of the screen. I've found it impossible to work on my tree on the iPad, and I don't like the app. I've even tried the new app and it's too limiting. I have worked my tree exclusively on the iPad and don't have another computer to use regularly. All help is appreciated!
