Earlier I said that there was this bad crashing problem with HamTechExam and that I better find it and fix it. Well.
I cannot claim any heroism here. It has taken me too long to get around to it, and the best thing I can say about the whole process is I don’t know how on earth this version of the app made it past the App Hub testers. It couldn’t possibly have worked in the state it was in. Maybe they were applying goose grease that day, and it just slipped in.
So, for what it’s worth (and for those who bought the app and couldn’t use it, that would be “not much”), the problem is fixed. It is in certification and perhaps in a day or so it will be published.
All I can say is: my apologies.
