Works as described, except IB v3.1.2 doesn’t allow me to disconnect the original menu (named OtherViews) from the popup button, and I had to connect the new menu by setting the connection in reverse from the menu to the button (referencing outlet).

I end up having multiple menu connections – seems to work, but doesn’t feel right. Any suggestions? Thanks again. The original menu was driving me mad.
