[Leica] Nikon Scan problems

[hlritter at bex.net (Howard Ritter)]

Nikon Scan 4 has started saving scans it makes with my Super Coolscan  
LS-5000 as TIFF files even when JPEG is specified both as the default  
file type under Preferences and in the dialog box that pops up when  
setting up batch scans. I have repeatedly switched back and forth  
between JPEG and TIFF as the file-type specification and nothing  
changes. The file log correctly notes that the files were saved as  
TIFF, despite what the dialog box says. Everything had been working  
properly until today. I'm saving my scans as highest-quality JPEGs  
because they take up only about 5% of the space that TIFF requires,  
and when looking at full-screen representations of the same slide side- 
by-side from JPEG and TIFF, I can't tell one from the other. So I  
decided to save the space. Does anyone claim to be able to tell the  
difference on screen or in print between maximum-quality JPEG and TIFF  
or any other lossless-compressed format?

I have even downloaded a fresh copy of Nikon Scan 4 and installed in  
on my Mac. I have downloaded and run (without protest) the v. 4.0.2  
updater with no result?the "About" box for NS still tells me I'm  
running v. 4.0.0.

I am completely flummoxed. Of course, customer support is closed over  
the weekend. Any suggestions?
