Chromium Portable cannot work with Google Pinyin 2(A chinese input method)

Many chinese users are annoying at this problem.
When I use Chromium Portable,I found Google Pinyin 2(A chinese input method) cannot launch at all,but when I close Chromium Portable,the input method is OK then.
When I use Chromium,no problem at all.
So I think maybe there's something wrong with ChromiumPortable.exe
