PHP JavaScript Tooltip Generator Class 1.1

PHP JavaScript Tooltip Generator Class is a PHP class that can generate JavaScript tooltips. The project works on all major browsers, but transparency is not supported on Opera.
In Internet Explorer, the tooltips show above HTML SELECT elements as they should. The appearance of the tooltips is template driven. Only onmouseover/onmousemove events need to be sepcified, not onmouseout.
Further suggestions, comments and requests are welcommed.
Id also really appreciate if you could send me links to the web pages where you are using the class so I can give them as refference and convince more people to use it. Thanks!
The code is heavily documented so you can easily understand every aspect of it
Enhancements:
- in Firefox, the tooltips were showing up in the right position only the first time; after that, the tooltips would show in the top left corner of the screen.
- "Sticky" tooltips can now be created (tooltips that follow the mouse cursor) by calling the "show" method on the onmousemove event rather than on the onmouseover event.
- In Internet Explorer, the vertical scrollbar no longer appears if a tooltip is shown.
- Automatic tooltip re-positioning has been improved in order to keep the tooltip in the visible part of the browser window if it would "flow" outside.
- There is some code cleanup.
