I used to have clean reports on the broken links. Now, I am seeing some issues with the Coffee skin and custom-toc-images. I don't use the Coffee skin; I toyed with it once then abandoned it. My new output preset was created after I decided against using Coffee. I cannot find any reference to it within any of my files. I don't know why the output reports broken links to custom-toc-images. I'm obviously not looking in the right places.
