When I changed the default language in Options/Language Settings/Languages, the
Spellcheck features stop working.  Both Check and AutoSpellCheck fail to work. 
Check will start at the top of the document and go to the end and not find any
errors.  AutoSpellCheck will not underline any possible spelling errors in red.  

This problem has occured in all the OOo-2.0 Snapshot Builds and also the 2.0
Beta (1.9.79) I have installed.

The dictionaries (DICT, HYPH & THES) were downloaded and installed using
DicOOo.sxw (as root) and installed globally.  I changed the default language (as
user) to : Language of : Locale Setting = English (Australia), Decimal separator
key = (ticked) Same as locale setting, Default Currency = AUD, Default Languages
for Documents : Western = English (Australia).  I have also checked language
being used by highlighting a word on the document and gone to
Format->Character->Font, which says English (Australia).  The English
(Australia) dictionaries are ticked as installed in all pulldowns.

I have tried using OOo-1.9.87 as root and SpellChecker still fails to work.

This appears to be the same problem as Issue#18370, but when I use OOo-1.1.2
(FC2) the spellchecker works properly.
