"When the icon lock is enabled, the rating & label bar is now also disabled (unless the Alt key is pressed while clicking" works in general, but now the whole area including the image is then disabled.
Even when just selecting an image by clicking in the middle of the image, the warning appeares and there is a sound signal; warning can be disabled with option "don't show again", but not the sound signal.
Thanks for testing. It was working correctly on for the tabular layouts.
I have fixed this for the next regular release.
