Thanks OldVicar, there's a bug in the 0.9.8 release whereby you'll get that exception if you double-click on a route segment where one of the ends is not on a recognised waypoint. It's been fixed ready for this week's release.
There are a few technical reasons why printing the chart displays isn't currently available as well as my fear that someone might try and use it as a "chart" in the cockpit. I can imagine the enroute features window becoming printable before the main map is, but neither will happen before version 1 release.
The map should remember the last thing you were looking at, it certainly shouldn't take you back to the south-west every time you start it.
