Hi to all. I am fairly new to flight simming and I have a question.I have RC4.3 installed and it seems to be working just fine with my set up the only issue at this time is that atc seem to be a little anxious for my replies to change controllers.I have Multicrew installed and it seems to work fine but when i get a request to go to any other controller either centre or airport tower or whatever.I reply and with in 2 to 3 seconds before I can set the frequency it asks me again. I am not sure if it is a problem with RC4.3 or Multicrew can anyone point me in the right directionthanks for the help in advance.Flying Big D
