rufowler's post in EZdok not saving certain settings on exit was marked as the answerWell after spending way too many hours trying to figure this out, and after resisting the urge to get 1.17 because of the many issues people seem to have running it with Win 8 / 64-bit, I went ahead an installed the newest (beat?) version. Happily, it cleared this issue up right away.
