This script was tested with the following systems and browsers:
- Windows XP: IE 6, NN 4, NN 7, Opera 7
- 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
- To hide a tooltip, use this syntax: toolTip()
------------------------------------------------------------------------------------------------------
EXAMPLE:
<a href="#" onMouseOver="toolTip('Just a test', 150)" onMouseOut="toolTip()">some text here</a>
