When you click on a specific book on the left side, you get taken to that book. Two or three pages in is an internal ToC. The internal ToC works fine with ADE for Windows and ADE on the 505. Now to make this better would have been to have a second level set of ToC under the main ToC in the external ToC. But it does work fine as is. Seems Hanlin's ADE is buggy in that it doesn't follow internal links.
I think (if I am not mistaken) that this bug is central to the V3 and clones. If so, get all the MR owners to bug the heck out of Hanlin ot get this fixed.
