Settings live in the renderer's IndexedDB, and two failure modes made them look saved while nothing reached disk. A second app instance sharing the same userData directory cannot take the Chromium storage lock, so its renderer reads defaults and every write is dropped. The app now holds a single-instance lock and focuses the running window instead of starting a rival copy. The lock is requested after the userData override so E2E runs with their own data dir keep independent locks, and after Squirrel event handling. IPTVNATOR_ALLOW_MULTIPLE_INSTANCES=1 opts out for local CDP debugging. updateSettings() patches in-memory state before persisting and the submit path had no rejection handler, so a failed write produced an unhandled rejection and no user-visible feedback. SettingsStore now records which half of the round trip failed, and the settings page surfaces it through a dismissible error snackbar; the dialog stays open on failure so the save can be retried. Two follow-ups from review, both wider than the report: - a second launch now re-creates the main window when the lock owner has none left, so closing the last window on macOS no longer leaves a second launch quitting silently with nothing on screen - App.onMainWindowCreated() re-runs window-owned bindings for every rebuilt window, so the downloads broadcaster stops holding a destroyed window. This also fixes the same bug on the pre-existing dock `activate` path. Closes #1156 Closes #102
