Walter,
I was flight planning a trip to Charlotte, N.C. from Utah and was planning my fuel stops. I put my finger on airports along the way, select 'Airport Information' and decide if I want to use that airport or not. The method worked well all across the country except for the Cheyenne and Charlotte sectionals. On these sectionals when I touched an airport I would get the dialog box pop up but when I touched 'Airport information' the box would disapear and take me back to the map. I then remembered that these sectionals were out of date. I think they exspired on 28 July and I was flight planning on the 29th. Anyway, I updated the sectionals on the 30th and now they show 'Airport information' just fine using the above method. I concluded that the problem must had been connected to the exspired sectionals.
Please let me know if you need any more information.
