I have three dictionaries installed, Langdao CHN-ENG, Langdao ENG-CHN and Oxford Bilingual CHN<->ENG. It seems in the bilingual dictionary I can only look up English terms, if I type in Chinese words the defintions are always pulled from the Langdao CHN-ENG dictionary (I don't know if this was the same in QStarDict because I couldn't even input Chinese characters!). This may not be a problem with MStarDict, it could be the dictionary is not two-way, I don't know how to check.
