If hitting "Ctrl-Z" doesn't do it for you, (autopilot altitude hold), then try "Shift-Z" instead. That will display the coordinates in the top-left corner of the FSX screen.
Or, you could use a freeware program called "Snapper" to take the screenies that need coordinates on 'em. That's what I would've done if I'd thought of it.
Thanks Spud. I figured out where he was talking about, just by the picture. It's the ship docks around the corner from Prince Rupert. I went right to them. But coordinates would have been better.
