This script was tested with the following systems and browsers:
- Windows XP: IE 6, NN 7, Opera 7 + 9, Firefox 2
- Mac OS X: IE 5, Safari 1
If you use another browser or system, this script may not work for you - sorry.

USAGE:
Use the toolTip-function with mouse-over and mouse-out events (see example below).
- To show a tooltip, use this syntax: toolTip(text, width in pixels, opacity in percent)
Note: width and opacity are optional. Opacity is not supported by all browsers.
- To hide a tooltip, use this syntax: toolTip()
------------------------------------------------------------------------------------------------------
EXAMPLE:
some text here
