Dave , if you read the last two post on the thread " Small problem on contacting ground" You will see that I discovered something wrong with the PF display folder. First the ini was incorrect,, which I corrected, and it still would not work, I finally had to delete the entire folder and replace it with one from my backup drive, that was made two months ago prior to my reinstalling PF3 last week. So this defective PF3 display was from your downloaded install folder that I did last week. I wonder if this could be causing the problem with the taxi to terminal. Anyway, on on your forum, I read that someone else had the same problem with PF3 display with their file not working and they had to install a backup file.
