<EM>> I tracked this one a bit further. It does not exist in

|

|

<EM>> I tried snapscan-0.7, snapscan-0.8 and they work as well. The problem
|
|
</EM><BR>
|
|
<EM>> only happens with snapscan-1.0 (the new snapscan-source code) and
|
|
</EM><BR>
|
|
<EM>> newer.
|
|
</EM><BR>
|
|
<EM>> This would confirm that this is the same pb Lawrence Glaister
|
|
</EM><BR>
|
|
<EM>> experienced.
|
|
</EM><BR>
|
|
<P>There was a major rewrite of the SnapScan back-end between 0.8 and 1.0, and
|
|
<BR>
|
|
the author abandoned the work a few percent from the end. This would
|
|
<BR>
|
|
explain a number of issues people may be having when they say Sane 1.0.1
|
|
<BR>
|
|
worked, but later versions do not. The author not only did not finish, he
|
|
<BR>
|
|
also did not possess all models of scanner to try his new code on. Most
|
|
<BR>
|
|
people aren't very good at feeding back useful bug reports, so......
|
