It’s just come to my attention that one of my apps (HamTechExam) is blowing chunks upon startup, failing to function.  When I first heard this I thought that it couldn’t be possible, since the other two similar apps (all running on the same basic code) were having no such problems.  But when I checked my own copy of the app it did not work, confirming it.  Really hard to understand how this was possible, since it was supposedly tested by Windows Phone personnel.  I know it was working then.  Perhaps it was the last update to WP7? 

Anyway, I now have 3 bad reviews in the Marketplace, which is unfortunate.  I am going to figure out what the problem is tonight and hopefully get this squared away.
