I was able to elicit the crash. I actually went back to v4.20. Leaving for M10 in 2 days. Mother brothers. That was close. Dear Garmin, I hate you, (I love you), I hate you... if you'd have called 4.40 a beta release, all would be forgiven, but noooo..... therefore: :fyyff Massive thanks to the usual suspects for the heads-up, and the easy access to the 4.20 file, and clear instructions for the downgrade. Deep breath. Everything's gonna be allright. I think I threw up there a little bit for a second.
