What are these light green colored circles and rectangle on the IFD 540 FMS map?     They appeared and then disappeared a few minutes later.  I musta been asleep when Avidyne training videos discussed these symbols.

Those are areas around airports where terrain awareness is inhibited.  In version 7 of the pilots guide, they are described on page 4-32.  In version 8 (the 10.3 version), they're described on page 4-44.

Those appear to be the FLTA runway suppression areas around the three paved airports shown in this screenshot. The three private airports have circular FLTA runway suppression areas because their runway directions are not defined in the nav database. The runway at the public 1T7 airport is in the database and that leads to the rectangular FLTA runway suppression area. It appears that the IFD airport filter is being used to not show the actual airports. 

The IFD airport filter does not appear to filter out FLTA runway suppression areas around airports that are being filtered from display on the IFD map. The FLTA runway suppression areas only display within 10 NM of the aircraft's position and altitudes within approximately 3000' AFE.
