How to use kanji-char on multi-editable-text

Hi, 

I am trying to use kanji-character on "multi-editable-text". But the behaviors
are strange. 

For example,
 (1)When inputing kanji-char by keyboard, garbage characters are displayed.
    (But, "set-text" or "value" are no problem.)
 (2) When editing kanji-string on multi-editable-text,
    - pressing Backspace-key --> a backward kanji-char is broken.
    - pressing Backspace-key once more --> delete a backward kanji-char.

The behaviors of "editable-text" are perfect....

Please tell me how to use kanji-char on "multi-editable-text".

Environment:
 *LOCALE* --> #<locale "Japanese_Japan" [:crlf-932-base] @ #x20d2df92>
 ACL6.0(patched "all new and updated patches")
 Windows2000

Thanks.
