Tooltip on Table of Contents?

I think Ben's soultion is the only one. You might consider to use images hidden by default, instead of text boxes. Do as follows (might work, can't tell you for sure):- add an image on the same layer as the the chapters- hide it by default- add an transparent button on the same layer- make it toggle visibility of the image on mouse-in and mouse-out- position the button over an item on the TOC- Repeat for all itemsNo guarantee it will work, but its worth trying. Perhaps Lextensions will help you out as well?
