I find similar problems with greyscale and
lineart modes, which also do not terminate
properly.  
This may simply be a problem with the 
scanner hardware.  However, since the color
mode works most times rather well, I could
use this scanner.  But a preview would be 
quite helpful.
My question is:  can I somehow patch the 
backend or elsewhere to force the preview
to terminate at a preset size?  
Suggestions are welcome.
