According to the Windows API documentation for ::GetMenu the return value is undefined if the window is a child (has the style WS_CHILD). Also, ::SetMenu will fail if the window is a child.
OWL does not take any notice of this. GetMenu and SetMenu are called without ensuring the window is not a child, while ignoring any failures.
