Well, under Windows95 it usually never did backtracking. When it did,<br>
|
|
it only backed up half the number of times it does with sane. This<br>
|
|
was with the little cheap controller it came with too.<br>
|
|
<p>
|
|
There had got to be a way to get it as fast as under Windows. My scanner<br>
|
|
is backtracking every half inch sometimes. Under Win95 it always moved at<br>
|
|
least a couple of inches before backtracking.<br>
