Cannot type some characters using hanyu pinyin IM in Snow Leopard

[Azastorr]

Hi Everyone,

Since, I upgraded OS X to Snow Leopard, I cannot type some characters
like dunhao (頓號 in chinese, which looks like this: 、), yinhao (引號 in
chinese, which looks like this:「」) anymore. Before upgrading, typing
those characters was easy, you only had to press "." key, then press
SPACE key twice and RETURN key once. This issue seems to be unrelated
to upgrading but inherent to Snow Leopard native implementation of
hanyu pinyin input method.

I am writing my thesis in Chinese, so I really need to find out if
there is any better way to type than using copy/paste...

Any help would be really appreciated.
