Thanks for all of the replies. I had already seen both tooltip.js and
prototips. tooltips.js does not have enough functionality for me. I
need the ability to leave tool tips up so that the user can close them
and position them more specifically.
As I mentioned, I did try to implement Prototips, but got an invalid
object or object does not exist (can't remember which one), every
single time I tried to do anything with it. Perhaps I will give it
another shot, but I spent a couple of hours on it already with no
success.
