I found a design error in LRc regadring the creation of HDR or Panos.
When rendering a new image either as HDR or as pano and use 'Auto Correction' settings LRc will create a new rendererd image and doing some Auto Corrections on that picture. If you take a look into the protocol you find only one entry, that is 'Import'. This would be fine if importetd picture would be the rendered pic with auto corrections. But if you click onto 'Import' in protocol the picture gets reseted. I think this is an design error. Protocol should either show two entries for Import and(!) auto corrections or 'Import' should be the picture with(!) applioed Auto corrections.
