folder thumbnails in special folder corrupted

My folder preview thumbnails (folder thumbnail view) have become
corrupted. All thumbnails, regardless of what the folder contains,
show a picture that I was trying to set for one particular folder of
photos. I was able to correct this for *almost* all folders by
deleting the Windows\Shell\Bags, BagMRU and DUIBags entries in the
registry for both current user and USERS, however this has not
corrected the problem for my folders at the root of one of my drives.
For these folders, every thumbnail still displays a preview of that one
particular folder. So on my D drive, I have about 15 folders, all of
which display as a thumbnail with the same image preview in it
(although a few display thumbnails of the pictures they contain, or
nothing at all.) Using the folder preview property sheet for any of
those folders has no effect at all (including changing the folder type
and trying to reset its view.)

How can I fix this?

Thanks!

Apparently, it's even worse than I had previously thought. Dragging an
image into a folder also causes the folder to reset its image to
something completely unrelated - the thumbnail image for the parent
folder! Any idea how to fix this too?
