Not sure when this started, but I think it's fairly recent: Even with the "Delete Cropped Pixels" box checked, Photoshop does *not* delete the unwanted pixels.
This causes a noticeable slowdown in my work doing photo enhancements. I often scan multiple photos at a time in high resolution then crop them into individual files. With PS now *not* deleting the pixels upon cropping, every adjustment I apply is applied to the size of the original large scan, not to the smaller single-photo file like I want. PSD file sizes are much larger, too, of course.
Is there somehow to get PS to revert to the correct action to delete everything but what's inside the Crop tool bounds when "Delete Cropped Pixels" is selected?
