No scroll at all on Safari

Hi,

I have created a test page with only simple text to show you :

http://fredwps-global-media-holding.pf2.wpserveur.net/test-page/

On Safari (OSX, last version), the content doesn’t scroll at all.

On Firefox it works only if I split the content in 2 rows. But with one big row of text it doesn’t srcoll too.

Can you help ?

Regards
