Background. First-time user of Aperture 3. Latest version installed. Using latest version Snow Leopard, on a MacQuadra, 7GB Ram, etc.
I processed all the images from a week-long shoot; no problems.
Two days ago, started shooting baby photos (my brother and his wife's new addition); variety of cameras (D700, G1, S90, D200).
Imported images into projects organised by day (and, incidentally, camera).
Import goes fine; then as I select an image, it turns a dark green; a message saying that the image was processed in an earlier version of Aperture (not the case) and that it needs reprocessing. Select 'reprocess'; no change, but then the Raw Fine Tuning window appears with its "Reset adjustment" arrow; this when clicked returns the file to expected—but not on all images; some stay dark green.
I have checked on the Apple Discussion boards; it seems this is a bug, but the suggestion to find the "Raw Decode Presets.plist" is unsuccessful, because this can't be found in App. Support, where it's supposed to be.
Unsettling for a Pro App, to be sure. All suggestions gratefully received. TIA, KL
