Ls8000 plus silverfast AI5.5 using Holder FH 869S

Hi,

I have a problem with the silverfast-addendum to my new scanner:

When using the holder for stripes I haven't discovered yet, where to

align the frame offset before scanning like in the original nikon

software. I only managed to see the correct frames in the overview

before prescan. But selecting a frame and doing the prescan again I

get an offset which I can't adjust. Is it possible to use silverfast

with the FH 869S Holder??????

(from silverfast I didn't get an answer yet).
