[Vista] Folders Look Weird after Update

[agoodfella]

OK this is a little strange, but after my Win update last night, some of my folders look strange (I can still access them).

The easiest way to explain it is 90% of the Folder has an Icon on top which is best described as a blank white page with a turned corner... Only get this is Thumbnail view. Other views look ok.

It's annoying though since this is my media subfolders and I always use Thumbnail view.

Any help?

Thanks
