To close Xpadder you need to right-click on the tray icon for it and select Close (or you can mouse wheel click it).
If there are unsaved changes made to any Controller or Profile files Xpadder will ask you if you want to save any changes.
Once the icon disappears from your tray area then Xpadder is closed.
If you shut down or log off Windows before closing Xpadder then Xpadder will close itself automatically.
If there are unsaved changes Xpadder will block Windows from shutting down/logging off until you have replied to Xpadder's questions about saving.
