Flight Planner Bug

Been using the flight planner lot recently and remembered a rather annoying bug. If you setup a flight plan, click OK and save it, and then go in later and change something (say add an airport to the route) the OK and Save buttons will not activate, you either have to remake the flight plan from scratch (aka "find route") or load the flight plan you saved earlier. Given the default naming convention, finding the right flight plan can be annoying. (Especially if you don't recall the name of the airport you were at.)"Let me help you out. You're cleared to taxi any way you can to any runway you see."
