Hi Mel,
What is this feature supposed to do and how is it supposed to work?
When you select a group of thumbs you must right click and use the menu item for refining multiple - it's near the top of the list - NOT the bottom item for a single image.
Using this method works through the images in thumb order.
See screen shot attached.
When you need to refine a group of images in a particular order, place the images in the queue in the sequence you want to use for refine. Select all images and then right click over the preview and select the Refine option.
See second screen shot.
In both option above, the arrow keys and copy icon will be "live", see 3rd screen shot with the icons ringed in red.
