Thumbnail/ Preview Question

Question

I have used Aperture since the start.... but i am getting a strange behaviour with thumbnails/previews.... imported raw files from a Canon 1DS MK2 in to a new project. Activity monitor shows the processing of the files (1,146) i am then getting previews that look faded.... until i turn off 'Quick Preview' and it will load the properly saturated preview. I have rebuilt the thumbnails and reprocessed a few times..... and when this has finished there are still a mixture of good previews and faded previews. Makes it very hard to edit properly.
I am using a referenced project with the images stored on an external FW800 drive.
Any ideas ?
Thanks.

Maybe it isn't the smartest way, but this should work:<br /><br />... call info.Parse (host, stream) etc here - the usual stuff<br />{<br />     // find biggest jpeg image for preview<br />     unsigned int subMaxW=0;<br />     int subMaxI=-1;<br />     for(unsigned int i=0;i<info.fIFDCount;i++)<br />     {<br />          dng_ifd* pIFD=info.fIFD[i].Get();<br />          if (ccJPEG==pIFD->fCompression && 1==pIFD->fNewSubFileType)<br />          {<br />               if (pIFD->fImageWidth>subMaxW)<br />               {<br />                    subMaxW=pIFD->fImageWidth;<br />                    subMaxI=i;<br />               }<br />          }<br />     }<br />     if (subMaxI>=0) // load desired jpeg preview<br />     {<br />          unsigned int i=subMaxI;<br /><br />          dng_ifd* pIFD=info.fIFD[i].Get();<br />          if (ccJPEG==pIFD->fCompression && 1==pIFD->fNewSubFileType)<br />          {<br />               // seek to pIFD->fTileOffset[0] and load jpeg<br />          }               <br />     }<br />}
