also remember you have to enable all devices to connect under the BT settings because the mouse is not paired
otherwise the mouse can't reconnect and you have to enable it each time (axim initiated connection)
The mouse itself initiats a connect on a click event so as long as you have the above enabled, BT was enabled on your axim before the mouse was turned on and you click the button on the mouse, it should reconnect every time.
The mouse has to be started after the axim has BT enabled as it will do a quick discovery, it will only try a connect to visible devices, it does not appear to do a discovery every time it tries to connect, only on start up (when it's first turned on) so will not 'see' the axim if the axim enabled BT after the mouse was turned on.
