Problem with tipsy

Hello,

i use the http://onehackoranother.com/projects/jquery/tipsy/#examples plugin in this page : http://www.trouvetongull.info/recensement/tableau.php?code=4

I have a problem: i can't use nw or sw effect, it's like north or south in reality.

See my <th> for examples.

What is the problem ?

Bye.
