Wow! Such a quick reply from you all is fantastic, and all my questions have indeed been answered!
Running Version 1.4, so no problems there. Found the documentation in the game folder, having a so so manual is better than none at all! The keyboard reference card is very helpful.
Found the radio messages - thanks
Just another cheeky one - what is the contact reports option for?
Nice to know that I can install GWX and get a great manual too, I'll cross that hurdle when I decide to install.
Thanks again for all your great answers, this is indeed a great community!
