The reconnection feature isn't implemented yet, so the device don't reconnect again. In some windows stacks is possible to reconnect without pairing the device again, the process are something like this: 1- Click in the bluetooth icon in the tray and choose "Show bluetooth devices" 2- Click in the device already paired and a menu list will appear, one of the options are "connect". Note: this is not standard across windows xp systems, I already seen systems with and without this feature.
