I am running Photo Mechanic Plus Version 6.0, build 6424 (aa9739e) on an iMac Desktop, running Catalina 10.15.7. With the latest update (sometime last week?), I notice that Landscape images cannot be rotated Left/Right to Portrait orientations when appropriate. Attempting to invoke the same commands from the appropriate drop-down menu does not work either.
I manually rotate these images in the Finder and when Photo Mechanic regains the focus the images are then rotated ... if this is helpful.
No bit deal--I just rotate during the scan, or when scanning batches, rotate within the Finder .... .
