I have implemented the "simple tooltip" from chapter 5, item 17 of "Jquery Novice to Ninja". It works beautifully when run on localhost, or on the live site with 'www' in the address.
See it here: http://www.buckspringsresort.com/specials.html
Try it with & without 'www.' The tool tip is attached to the "Green Company" link at the bottom right.
Am I missing something important?
My bad: this seems to happen only in Firefox; I bet it's an add-on causing the behavior, but it's still kinda strange to me. Thanks...
