I encountered a lost-focus problem when I launch a metro window as dialog window (new MetroWindow().ShowDialog()). I remove GlowWindowBehavior in my metro window style.
Because I found that it will create 4 windows around the main window in order to implement shadow effect, and sometimes one of them will capture the focus. You can try to custom metro window style and remove GlowWindowBehavior.
