I open RootsMagic 7.6.1, go to Tools/File Options/Ancestry and click on "Disconnect from Ancestry tree." RootsMagic locks up and I have to use the Task Manager to exit. The task manager reports "RootsMagic not responding." I'm actually not sure whether the Ancestry Tree is actually linked or not.
There's been so much trouble with Ancestry that I'm trying to disassociate RootsMagic completely from them although I plan to continue using Ancestry as a research tool.
