Press and hold Shift, then right-click the Filr icon in the Windows system tray.
If you upgrade the Filr Desktop Application while a previous version is running, the overlay icons might not display. For more information about this issue, see the Filr Desktop Application Release Notes on the Filr 3 Documentation website.
