I have tested the software on Windows (version 0.9 dated Dec 31). The
sanedll and scanimage appeared to work properly - I could scan an image
from Win95 with the scanner on my Linux box, and the .ppm images were
identical.

However, I had problems with the TWAIN interface using Adobe PhotoDeluxe
that was shipped with the UMAX 1220S scanner. I configured the .ini
file to point to my scanner, and the TWAIN_32 interface appeared OK.
When I selected the TWAIN_32 source, WinSANE Ver 0.9 started, with my
scanner selected.

However, some of the parameters (eg Mode, Resolution, and Scan-size) in
the GUI did not match what was in the .ini file. I tried scanning
several times, and each time either WinSANE would report "Scan failed"
or I would get a white image back. There was a flicker of disk activity
on the Linux server, but no scanner activity at all. I was watching
"top", and did not see if saned started. However, my scanner kernel-module
was loaded, so I assume saned started and stopped very quickly.

I also tried running "saned -d 128" as root to see if there were any
debug messages, but nothing appeared on the console. However, no debug
messages appeared when I used scanimage and xscanimage on my SANE server
either (bug/omission in saned or stupidity on my part?). Unfortunately
I can't see what's wrong with WinSANE, since the source isn't available...

Cheers, Andreas
