Not sure.
close directory in the example is this

void CloseDir(int id) {
tree1.RemoveChildren(id);
}

I changed it to this but it didn't fix the problem

void CloseDir(int id) {
tree1.Close(id);
tree1.RemoveChildren(id);
}

so I guess the minus sign is showing there's no children.
I'm wondering if there should be no plus or minus icon on a node that has no children - but then for this example you wouldn't be able to re-populate the node so perhaps remove-children isn't quite the normal thing to do in CloseDir.

[Edit] - oops, didn't see your second answer before I posted this. Thanks.
