Last night I had full support in windows explorer for CR2 thumbnails. Today I turn it on and the thumbnails pop up untill they all are showing the image, then they all turn to an icon. Close the folder and re open, it does the same thing. 1 by 1 they show till all the thumbnails are showing, then boom! they are gone and back to icons!
I have been looking for some reason to use bridge, I guess I found one.
BTW...Canon updated the RAW codec on 11/24/2009 for the 7D if you dont have it yet.
