Hello, I have been using your code above, it's been very helpful thanks. I had a slight issue where on one page I needed to update the title on a click, in order to do so I had to change the content of the tooltip div, this meant updating the tip variable by adding tip = $('#tooltip').html(); to the remove action before the original title is updated. The issue with this was that when a user mouses over consecutive tooltip areas quickly the title content from one would get copied to the next. The solution was to use the finish method tip = $('#tooltip').finish().html(); , accidentally this improved things in general as on our project we have a number of objects with tooltips next to one another and it was often the case that a quick mouse movement could bring up multiple tooltips overlapping one another. Adding the finish method as described stopped this behaviour. Just adding a note here in case anyone else finds it useful in future.

Hi. Is there a way to have the tooltips work on touch devices? They show up but would rather you can tap anywhere for the tooltip to disappear rather than on the tooltip itself.
