The AllWebMenus Web Tooltips Addin is free and included in AllWebMenus Build #810 or above by default.
It is actually used to add stylish, feature-rich html tooltips to menu items and replace the standard browser's tooltip on them.
However, the javascript tooltip should be created by a licensed installation of the separate product that actually builds the tooltip: the "Likno Web Tooltips Builder".
