When I leave Skydemon open on my Windows PC (Version 3.6.0) and put the PC in sleep/hibernate mode for re-awakening later, and come back later to resume using Skydemon, I'm told it is working in offline mode.  There does not seem to be any "resume online" button?  It seems that then to get weather/notams etc I have to shut down SD and re-open in with my username and password - am I missing something?
