This happened to me once before, and I don't remember how to get them back. And I've searched in the forums for the original link and cannot find them either....
At the top of my Logos (on a mac) I've got several icons for favorite books - some of them have lost their logo....

Notice the missing one between the books listed there. There is the NCV there, but no logo. I can put a stock image there, but I'd prefer it just worked properly.... I know I have to rebuild something, but any ideas?
