(User interface is set to ‘Try to use existing window’)
I best give an example.
click a playername in chat to open their info-window. then move another window in front of it.
if you click the same playername again, nothing happens. the window remains in the background.
only if you click another player, the window is moved on top.
same for all item-info, which uses the same type of window.
(stations, planets etc)
same for ship info windows
maybe more.
this behaviour began at downtime thursday 19. febuary, I think.
