Why the ATC is speaking continuously, randomly?

• Make sure the keys you use for requesting are not used for any other purpose in any other application. Let's say you change the flaps position of your plane with the F key, when you will press this key, you will probably request for a flight clearance (because in the defaults settings, the F key is used to request flight clearance).
• Note that you can have the same problem with any other application than X-Plane: once EasyATC is running and the ATC is enabled, every keyboard input is handled, whatever EasyATC has the focus or not !
• Make sure you have at least two different voices installed so that the pilot and the ATC speaks with different voices. If not, it sounds like a horrible monolog!
