Hello fellow RB users, I am a new user and have been using the radar box for a week now and have enjoyed every moment so far. However when using the alerts feature to view airbus A320 or B74* movements from Heathrow, I have experianced a complete system lock up requiring that I reboot my computer (XP pro). I am unable to reproduce the problem, it seems to be random but may follow multiple alert responses. Is this a known feature with a fix?
