Chinese Language Input Problem on MindManager Web

Hello, I have a problem with Chinese language input with MindMananger web version and need a little help.

When I create a new topic and start typing in Chinese Pinyin, it seems the first letter is always shown as english letter instead of being part of Chinese Pinyin to form a character. See example below: when I type ma, m become an English letter instead of forming chinese character. So I have to delete and start typing again, and then it's all right.

This problem occurs on Windows and Mac with different Chinese Pinyin type methods. So I guess it's only related to the web version and doesn't relate to OS or Chinese Pinyin Method.

It would be great if you could fix it soon. Thanks so much! Jay
