I think it may be problem of my Video Card Driving.
before i install video card driving, the 输入法 can be used.
after that, it doesn't work and the menu of "openoffice word processor" have wrong codes like "??? ??? ???", but when i root in english language, there are not these problem.
my video card is ATI Radeon.
i am not sure that i have installed the driving of my video card correctly. Is this the problem?
