Digital BW, The Print

I just bought a Nikon Coolscan 8000 yesterday, and am getting very good 
scans from the outset, it seems, The only problem is the 120 format film 
holder. 

Aside from the fact  the clips holding the negative in place seem to treat the 
negative very roughly in the way they clip hard into the neg edges, my biggest 
problem is I that the scanner does not scan quite the full width of the negative 
(and therefore edge/rebate as well) in the scan. It's cropping the last albeit 
small part of the actual image on the left side of the image.

Am I missing something here? Is there some way to increase the dimensions/
proportions of the area to be scanned somewhere? I tried placing the chosen 
neg in the middle of the holder but the scanner still read the image with the 
same cropping.

Oh, and also, my zoom buttons in preview won't work, They're grey, and so 
inoperative.

Any solutions/explanations much appreciated.

Thanks

Nick
