I had the same problem over the weekend with 1.50. Had only one area (Living Room) with two Insteon devices in the area (this area created under a previous firmware level). I created a second area (Back Yard) to hold two X10 devices. Now have two areas listed both with Back Yard name and the two Insteon devices were no longer listed. Deleted one of the duplicate Back Yard area names and recreated the Living Room area name. Perhaps it is due to the original Living Room area being created under an earlier firmware level because recreating the Living Room area name did not result in the Back Yard area name being changed. After recreating Living Room, I now have two areas, Back Yard with two X10 devices and Living Room with two Insteon devices.
