From the main menu, I click on Diagram > Save Diagram As... > Custo Diagram Type... and give it a name. I then close it without saving the actual diagram, as I just want the template, not the specific example with the defined root.
Charts tool bar button > Custom Diagrams > my new template opens with a dialogue box asking me to select the Root Person, which I do, and the displayed diagram is completely blank
Is that a bug, or am I doing something wrong?
