Hi redcrown on guard, Changing the CameraRaw plug-in does mean that there may be additional capability available in updated plug-in which is relevant for regeneration of thumbnails, and this is the way plug-in support has been designed. Your suggestion that changing the plug-in should not trigger to re-generate cache of thumbnails, will break the plug-in update happening independently outside of Bridge. However, if you keep the plug-in version same, and keep the cache location same as in previous version of Bridge (as I suggested in my previous message), then Bridge will not re-cache the thumbnails again. Thanks, Deepak Gupta
