This skill provides a robust implementation pattern for managing focus within WPF applications, specifically targeting issues where Popup controls fail to display or function correctly when the application loses focus to other background tasks. By utilizing the PreviewMouseDown event and IsKeyboardFocused checks, it ensures that the application window is automatically reactivated and focus is restored when a user interacts with the UI, providing a seamless experience for complex desktop applications that rely on persistent or interactive popups.
