FYI:  Xastir doesn't save the "Send Auto Reply" flag to the config
file.  When it boots up the flag is cleared.  If you get an
auto-reply message from an Xastir station the operator has
specifically gone to that dialog and set the flag since he/she
brought it up.  Doesn't mean it wasn't three months ago, but at
least it has to be manually set.

Another thing we _could_ implement, but we'd have to warn our users
about this change well ahead-of-time.  What sort of timeframe are
you suggesting?  A day?  An hour?
