If you have let it run you in full screen mode, your IME will fill the entire screen... because it is full screen... if you don't resize your UI to fill the screen, you will have an empty area.
I am a little confused because then you are also talking about turning off full-screen from the application with android:flagNoExtractUi. This a separate thing from simply not having an extract view. There were some issues with it in earlier versions of the platform, but it should work on 2.1 (and possibly 1.6).
