At last! Vista SP1 was released!
As soon as I installed, I cannot use my English Keyboard. It seems to be difficult to change the keyboard layout... MS doesn't think there are a lot of person who write Japanese with English keyboard, does it? I was very very frustrated!
However I can use USJP again by Trinity Works LTD. I felt comfortable and easy when I used it. It may be good if I won't be frustrated.
