Hey folks,

the reason for the described behaviour is found in the WindowChrome property. The CaptionHeight defines the height for i.e. dragging an movong the window.

By setting

WindowChrome.IsHitTestVisibleInChrome="True"

within the control needed to have a clickable behaviour resolves the problem.
