Problem: The overlay window, even when fully transparent or visually hidden (opacity 0), was still intercepting mouse events. This created a 'dead zone' on the screen where users could not click through to applications behind the overlay. This occurred because the low-level window hook was answering 'HTCAPTION' to hit tests regardless of the UI state. Solution: 1. Modified 'WindowHook' to accept an 'enabled' state. 2. When disabled, 'WM_NCHITTEST' now returns 'HTTRANSPARENT', allowing the OS to pass the click to the window underneath. 3. Updated 'main.py' to toggle this hook state dynamically: - ENABLED when Recording or Processing (UI is visible/active). - DISABLED when Idling (UI is hidden/transparent). Result: The overlay is now completely non-intrusive when not in use.
