the "Note (CJK)" tab can't edit Rich Text

After I have the "Format double byte language" box checked in the "Tools | Optiosn" window "Format Manuscript" tab, I do get "Note (CJK)" tab instead of "Note" tab in note editor and can input Chinese characters in "Note (CJK)" tab .

But it seems that I can't change the format (like font or color) of any characters(neither Chinese nor English) I just typed. In other word, the "formatting"toolbar doesn't work, the note editor acts like a plaintext editor.

Is it a bug?

When CJK editor is used, you

When CJK editor is used, you can select text and click the right mouse to select formatting options. The toolbar buttons won't work for the CJK editor.
