John, if this happens again, check to see if the MyLog.db3-journal (in the DATA folder) is getting big.
I've seen this happen a couple of times, where the MyLog.db3-journal just gets bigger and bigger and database updates aren't happening. It occurs when I've been using SQLite Maestro with Radarbox running, and would suggest some sort of database update conflict between the two programs.
Maybe Radarbox (or the SQLite database engine) gives up when it gets a database locked situation?
