I can't use boshiamy 7.0 chinese charactre input software in Mail/Subject?

I just upgraded to eM Chient 7.0.26687.0, but something unfortunately happened.
I can’t use boshiamy 7.0  chinese charactre input software in eM Chient 7.0.26687.0 Mail/Subject, but it’s ok when I key in words in Mail/Body. Why? Everything is ok when I use the previous version of eM Cleint 6.0.
How can I solve the problem? thanks a lot.
