1) Script Title:
Cool DHTML Tooltip II

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...mltooltip2.htm

3) Describe problem:
I've successfully implemented the Tooltip II script, which works fine under IE (6 on windows)

but under my own browser, Firefox (2 for mac) the tooltip dissapears behind the scrollbar of an multiple select, i've attached a screenshot.

Any ideas?
