I'm trying to build a complex usercontrol which is intended to be hosted in an Office TaskPane.
Tree: Excel/Custom Taskpane/Forms.UserControl/FormsIntegration.ElementHost/wpf.UserControl.
A 'non scenic layout' with an application menu DOES work as expected, but I can't get a Scenic Layout with a Backstage menu to work. When I press "File" tab nothing happens. When run in a wpf application the backstage menu is displayed fine, but not when run in an ElementHost.
