I updated Stellarmate to KStars 3.6.1 today. I noticed one unexpected behavior: when I minimize the Ekos window to see the KStars window (to select an object), then also the KStars window closes together with the Ekos window. To access the KStars window I only can move the Ekos window somewhere to the window border. When I open the Ekos window again then also the KStars window appears (in the background).
I checked with a backup of KStars 3.6.0, this behaves as expected.
