When I tried to Log-in, the LL oficeial viewer showed a message to force us into updating.
'UPDATE or QUIT SL'
I decided to uninstall LL's official viewer, and install firestorm viewer.
I found that the firestorm viewer' was less load and more excellent graphic, and worked far better than LL's viewer without problem.
Not a small number of Japanese are replacing their viewer from LL's to FIRESTORM.
I'm convinced they (and I) WILL NEVER be back to the LL's official viewer, even if LL fix this '2byte problem' .
There're no reason to quit using Firestorm, for now.
hasta la vista '**bleep**in official SL viewer!!!'
