Vista and Outlook 2007 language problem

[KL]

Hi,

I am using Vista Business with Outlook 2007 in my laptop. I set the locale
in Chinese (Hong Kong SAR) in regional settings. When receving Simplified
Chinese HTML email, it always display "plain text" with monster character.
It is fine for BIG5 HTML mail.

It has no problem with my other computer with XP and Outlook 2007 in my
desktop computer with same regional setting. Can you help to resolve it? It
made me mad!!!

Million Thanks
