Under View/Manage Areas, the list of devices in an Area has a Light Bulb to the right of each device entry. For Insteon devices, if I turn the device on manually by clicking on the ON switch, the Light Bulb graphic is changed to an illuminated light bulb. Selecting an X10 device and clicking on the ON switch does not result in the Light Bulb graphic being changed to illuminated. The actual X10 device does turn on. Not sure if X10 is suppose to work the same as Insteon and this is a very minor UI problem if it is.
