SubGraph Context Click

Hi again!
I want to allow the user to right click on a subgraph when it is expanded and copy and paste nodes into the subgraph. However, I have found that the context click event is only triggered when the user right clicks on a subgraph when it is collapsed. Is this correct? And if so, how can I make this event get triggered when the user right clicks on a subgraph when it is expanded?
Thanks!!

Does setting GoSubGraph.PickableBackground to true help?

yes it does! thanks!
