Lyx 2.0.6 Mac OS X Spell checker not underlying errors

[Miguel Ángel Artaso Landa]

Hi,

I've just installed Lyx 2.0.6 on Mac OS X 10.8.3. Since I upgraded the
version of Lyx, the spell checker is not underlying in red the words that
are not correctly spelled although when invoking the spell checker it is
stopping in the words that need to be corrected. Is someone else suffering
of this?

Regards,
Miguel A.
