Why does an error sometimes occur when starting the map management dialog?
A. There appears to be a bug in the handsets firmware which causes it not to respond fully when commands are sent to it too fast. Spitfire will automatically adjust the rate at which it sends commands to the handset when this error occurs. So keep retrying until eventually Spitfire finds the optimum rate for error free communications. Spitfire will then remember this and use it for all future handset communications.
