Tony,

Thanks for your input.  I don't think remounting the slides is an option for me 
- a lot of
them are my wife's and she doesn't trust my dexterity enough (probably rightly 
so!).

I guess I'm not surprised that positioning the focus point in a single position 
isn't a totally
effective fix - if it were Nikon would have incorporated it into Nikonscan.

It would just gall me to spend that much on a scanner and still have to worry 
about
focus.  (I cut my teeth on a Minolta Elite which had fixed focus and yet was 
sharp over
the whole frame.)
