I know it's mouse clicking and w/e, what I'm saying is that in Win7 it doesn't happen, so it definitely is a Win10 issue.
Yes, there is a common Orbital type, and ships and stations are (some of the) specializations of that type (Station icons are displayed on the top left of the Task Forces expander, Ship icons are displayed below that). So they are treated mostly the same way.
Now that you mention this, though, the Station class is also a specialization of Production Centers, not sure if it could be related to this. Seems to be an indexing issue of some kind.
Never noticed this.As for the galaxy map scrolling/lagging issue....I noticed that the borders of the sectors are "flashing" all the time...just a thought could you try turning this "flashing" off to see if it speed up the lagging of the map ?
