Hyphenation problem

[Javier Nieto Esteban]

Hi,
         I'm an Spanish newbie user of Lyx (really, I use Klyx in my 
Mandrake Linux). I have a problem with hyphenation... becouse the automatic 
one created by LaTex is incorrect.I want to swich off this option. How can 
I have no hyphenation ?

Thanks!!
