Okay, that's fine, but that's when the program closes, when I hit Enter after typing in the ICAO for the alternate. As I said relatively early, I found a workaround, so it's not affecting my ability to use PF3, but it's odd that a feature would close the program. Oh, and if I Skip Alternate, everything works fine as well. Thank you for the time you've spent on this issue, I'm not sure what else can be done at this point. I could try a reinstall, but not sure I want to go that far since I have a workaround.
