Resize OnBoard window

[H.S.Rai]

Seems silly question, but I could not find any wayout.

How to resize window size of "OnBoard" a on screen keyboard. I tried
it on my Tablet PC Compaq tc440, powered with latest Ubuntu 11.04

It so happened that it occupied full area on my screen. I tried
graphically, nothing happened; tried with ctrl + 0, ctrl + -; escape.

Tried to remove completely, reinstalled. But same result. It should
cover small area, so that I can use it, while seeing its output in OO
Writer (say).

Please help.
