Hi, Paul,

what about opening in *another* image editing application - same effect?
I have had the same problem with PS 5.5LE, the other way round - my
files would open too bright which is why I don't use PS 5.5LE that much.

Just in case there's still something important to be set in your copy of
Nikon Scan - I'll append the settings I use in text form. I use NS 2.5
which may be slightly different from 3.1, however.

Sorry for misleading you - it's actually RGB, not sRGB. I misread.

I have heard there's no such menu item with the newer Coolscans (LS-40
and 4000). If you are using one of those, you most likely won't find it.
Maybe the newer Nikon models can go without it - however, the LS-30
can't.
