Bridge CS3 shows no thumbnails??

Adobe Bridge CS3 has been working fine for quite a while. I have been having
some problems with my System (C) drive, where it and Photoshop CS3 are
installed.

I swapped out the C drive, and restored an image of the drive, and most
items are working OK. But I'm guessing that Bridge may have suffered some
"corruption", prior to when the image was made.

When I open Bridge CS3, it opens normally. with the files listed on the
lower left, but there are no thumbnails visilbe for any images. Momentarily,
I did see some for one folder, but now they are all not showing anyting at
all in the thumbnail or individual window on screen.

Just for kicks, I double clicked in the middle of where the thumbnails
should be, and an image then opened in Photoshop. So they appear to be
invisible, but present.

Any suggestions here? Is repair install needed, or is there a setting
somewhere that has gotten messed up, that can be simply fixed??
