RibbonWindow gets messed up

May 1, 2013 at 7:03 AM
I wanted to use a WPF-RibbonWindow in a new WPF Caliburn.Micro Application but the Title bar is displayed blank, even the close buttons are blanked out.
In a previous program I did something to Caliburn to stop that problem - but I cannot find that necessary step.
Do you have an Idea?
