It seems that many of the windows don't properly change when activated from another screen, if they're already open. For example:
On the Galaxy map and system view screens, if I click to open the system map when the system map is closed, it will correctly open it in that system, however if the system map is already open, it won't switch it to viewing the selected system.
Also, if I open up the system view screen by pressing the button on the system view, it correctly opens it up to that system, but if I use the hotkey F9 to open it, it brings up the Sol system instead. In addition, clicking the buttons for system view or geological survey while those windows are open, won't update them for the current system.
It's not a major bug, but it'd be convenient not to have to track down a system through a drop-down menu, or close and then re-open a screen to get it to go to the right system.
