Oh. Thanks. I wasn't aware of that. I had no idea what 'rootnodes' meant.
I can imagine that I am not alone in not understanding the term 'rootnodes' or what it implies in the setup dialog. Maybe a less technical, but more intuitive description would be useful. At least a hint window with an explanation would be handy. Or, even easier, don't make this an option, but enable it by default. Unless, of course, there is a strong reason not to have this enabled - which personally I don't see.
