<i>&gt; Then when it did actually start scanning the software thought most of the</i><br>

<i>&gt;</i><br>
<i>&gt; For the preview image it loaded something in the window before the scanner</i><br>

<i>&gt;</i><br>

Hi Bill,<br>
<p>
the problem is known with some scsi-controlls/drivers.<br>
I don`t have a solution for this. If you have another scsi-controller<br>
try that one or try to find an other driver for your scsi-card.<br>
<p>
Bye<br>
Oliver<br>
