Thanks Nicola. It does indeed work the same way for X-plane 10, although I just spent half an hour trying to left click on the name of the airport to bring up the ATC frequencies without success. I was clicking all over the screen - eventually I found it. The target area you have to click on is actually a tiny blue point just above the airport name. On the airport I was using, it was in the middle of one of the runways (also shown in blue) and just about impossible to see. …Hope this saves someone some time. Cheers, Algie.
