The UI is a little nicer now with knowing what state things are in.
So when a UI window is up, you can no longer click the ones below, this was leading to some weird states and crashes.
And also now the range rings only appear when you are actually creating a route, and they are needed. I'll need to add an extra "range finding" mode to airports as well, as you might still want to plan ahead and check ranges before you can make routes.
