[ubuntu] onboard keyboard doesn't work (unity)

view story

http://ubuntuforums.org – onboard keyboard app no longer works in unity. i have tried reinstalling it, updating, etc. the board will come up nicely when i highlight a field that can have text entered, however, i cannot - type any keys - close the window - move the window the keyboard seems to randomly highlight several keys at once. i have tried using the mouse, and my touch screen (lenovo x220t) but neither work, both behave the same way. what should i do to fix this? thanks!
