Hi!
True for almost all thumbnail/previewer/cataloger applications. I think the only ones that does RAW conversion to render the thumbnails, as an option only, are ACDSEE and BreezeBrowser.Adobe's Bridge and Lightroom update the embedded preview JPEG using the Camera Raw or Lightroom parameters, Bridge and Lightroom then cache the JPEG thumbnails for speed in use.
Count IfranView in. I tried batch processing from PEF to 25% JPG and it did work properly.
