As of a few days ago (sorry, can’t be more precise than that, but it’s less than a week and at least 3 days, probably 4 or 5), clicking the LP Store button at a station brings up the store window, but clicking it again no longer dismisses it, now necessitating closing the window in other ways - rather annoying (granted, not exactly game-breaking.)
Incidentally, while I’m here, a few months ago, station Undock got the same “treatment” but only with regards to the hotkey/shortcut - the UI button works to cancel the undock, but the assigned hotkey does not, which is also rather annoying.
Regards
