Thunderbird Dictionaries

["(Aesux)" <pere fedora linux gmail com>]

Hi,

I've migrated from Ubuntu to FC4. I'll like to taste it.
Now I'm finishing to tune it.
I've a problem installing additional dictionaries for thunderbird.
I try to install Spanish and Catalan dictionaries throw the extensions 
menu. It seems the process go fine. But when I restart thunderbird there 
is no new dictionary installed.

Any idea, any suggestion?

Thanks in advance,
