Vista - [Problem] Windows Vista Remote Desktop NON-English user swich lang

Hi,

I'm currently testing Windows Vista Ultimate in my firm for a month now. It
works great, I love it. However, there's one big problem with our Windows
Server 2003 to work with Remote Desktop in Windows Vista. Since, we are a
non-English user, we need to switch back and forth between English and out
local language all the time. However, we didnt' manage to use the language
switcher when using remote desktop with Windows Server 2003. My server works
fine with Windows XP, but for Windows Vista it didnt do anything when I tried
to press the key to switch to other language.

Hope you guys understand my problem.
I'm using Thai as my local language, and I'm using Grave Accent key to
switch between language.

I'm sure that there are many peoples who are a NON-English user will also
face the same problem.

Thank you
