We are aware of the issue you encountered. It is caused by a bug in the Silverlight plugin that is triggered when there are tab panes that contain elements that inherit UIElement
and panes that contain elements that don't. Currently we are tying to find a workaround so please bear with us. Until we have a solution you can make sure you only place UIElement
-based controls in the tab panes. Hope that helps.
