@DustyReagan: You should really really really avoid this:
> <img onmouseover="tipit(this, event)" ... /> Specifying the javascript like that makes for very obtrusive javascript, which we need to avoid above all things!!!! What about applying the "tipit()" function on domready, instead of creating the tooltip (which you will create on your tipit).... Would that kill your browser as well???? What about attaching a mouseMove (or the like) event to the "window" object and check for the object beneath???? Just throwing some ideas...
