We have had the same problem, and I have been forced to guesstimate
what I would have set the thresholds to.  Bad scene!!!  It would be
much better if in fact, once you change it on a file it remains changed.
Also, then if you don't happen to digitize the whole file in one session, 
you are consistent on your thresholds.
