As I seem to be proving -- I am a surfer more than a coder... here is something else I am making a note to myself to try... Several versions of "tooltips" one is a drupal module and some others for generic use

This drupal forum thread has a module linked in it to create Fancy Bubble Tooltips ... can't help but quote "goldentoque"

How in this day and age of quick development, and posting to the Internet how things can go from a posting of a question to two versions of a module in less than 12 hours...

That work is based on this JavaScript library Bubble Tooltips here it is the example: just roll over any link to see them in action.

Which lead me to another version without a graphic found at DustinDiaz.com JavaScript Fading Tooltips

Dustin also seems to be a podcaster click to give a listen The intro was a bit "super geek" my one wish would be web standards!! (maybe not my first wish...) ... so I liked it
