jQuery Tooltip Script

I always use this one here:

http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/

It has the option to both follow the cursor AND keep it's position, along with a few other helpful options. The css is also very minimal and therfore easy to change.

See there's this thing here called a search engine...

Okay, okay... I'll be more constructive...

My favorite is qTip 2. It does everything you want it to do. and you don't have to leave money on the table...

I use qTip2 from http://craigsworks.com/projects/qtip2.

By default, it does not move with the cursor. There are a bunch of options and some themes. The best part is that the developer answers all questions in his forum within a day or less.

Also here are some good ones meeting your requirement that it not follow the mouse cursor:

As a side note, I'd stay away from the tool tip plugin that's part of jQuery Tools by Flowplayer. IMHO, jQ Tools is poorly implemented, out of date and not supported very well by the developer or his community.

100 various solutions on this page (however, some are not jQuery):

The one I always use is: http://tutorialzine.com/2010/07/colortips-jquery-tooltip-plugin/

It's three short CSS lines to customize colors and easy to work with!
