If I save a route with an aircraft using NM and then I save the same route with another aircraft usìng SM (with different file name of course), SkyDemon memorize the last unit entered (either SM or NM). In fact when I open the two routes I'm supposing to find the two routes withthe  two different aircraft as saved with the  two different units as set-up for each single aircraft  ... is not the case .. Am I wrong? HELP .. thanks in advance. Furio
