<i>&gt; &gt; Hi,</i><br>
<i>&gt; &gt;</i><br>
<i>&gt; &gt;       Anyone out there ever run into the following with SGI/UMAX: Previews</i><br>
<i>&gt; &gt; and scans are all fine, at all resolutions and with color and or</i><br>
<i>&gt; &gt; transparency adapter, but only for scan files that do not equal or</i><br>
<i>&gt; &gt; exceed 4MB in size! For such scans, the scanner just stops a few seconds</i><br>
<i>&gt; &gt; into the scan, and a black or "black with white patches" image is</i><br>
<i>&gt; &gt; produced. When such a thing occurs, the little status bar that monitors</i><br>
<i>&gt; &gt; transfer of data to GIMP or whatever is blank. i.e. The box appears, but</i><br>
<i>&gt; &gt; no words or status bar is visible.</i><br>
<i>&gt; </i><br>
<i>&gt; The coolscan backend suffered from a very similar problem on SGI. The</i><br>
<i>&gt; workaround has been to limit the size of the data chunks read from the scanner</i><br>
<i>&gt; to 64K instead of 'sanei_scsi_max_request_size'.</i><br>
<i>&gt; </i><br>
<i>&gt; Probably more a workaround than a fix but since there was no perceivable</i><br>
<i>&gt; performance penalty I kept it that way.</i><br>
