It's relatively small compared to other IME system.
Moreover, I can simply copy & paste the chinese content (that I type) to OpenOffice. This way, we can get the font appearance even more beautiful & "professional". The great thing is about this software is: it solves the Asian language proble WITHOUT having to install the environment. So, it's really a hassle-free solution! Moreover, NJStar is an independent software, meaning that even under Windows, we don't really have to install it. Just unpack the content & start the exe then it should run. With that nature, NJStar works so perfectly well because it's not dependent on the Windows system itself. And of course: no font problem! This is a great software for anybody who wants to write Chinese/Japanese/Korean WITHOUT having to install the environment. And at once..., oddly enough, help to bring Linux to a better internationalization after... thanking the wine's project & developers...:)
