Hi Kerry,
this is an excellent bug report - almost perfect. The debug.txt can sometimes not be generated (four times .... on the left CDU) because either the code crashed too bad before, or the user hasn´t selected the "DEBUG mode" option in the PREFERENCES.
I believe that Tom has already fixed this bug in the next version coming up - there was a bad quirk in the STAR and TRANSITION selection process, that hit a lot of people...
I will forward this to him just to make sure it is the same error, and please do me a favour and check again after the next update, would you?
The N/S thing will also be fixed - just be aware that sometimes using the REFERENCE AIRPORT position is not accurate enough - especially on big airports. Use the GPS like you did, that should work fine everytime.
Thanks again, Jan
