LR4: "crop to same aspect ratio" (shift-A) often distorts image
"crop to same aspect ratio" (shift-A) command often distorts image when first applied. This happens perhaps 60-80% of the time. Perhaps there is some timing issue. If the distortion happens, undo-ing the Shift-A command and reapplying it always fixes the problem--i.e. the distortion does not happen on the redo after the undo. The distortion is that the image is stretched vertically compared to what it was before applying the command. I see this applying 16x9 crop to 3x4 image file. This appeared in LR4 and is not fixed in LR4.1RC2.
