I am using gok under Ubuntu 9.10.
I type 'gok' in the terminal and a small window with 9 buttons comes up... However, clicking on them does nothing.

How do I make this program work? Or is there a better on-screen-keyboard for Ubuntu?
Edit: now it does something but it shrinks to a miniscule (maybe 32x32?) window everytime I click a button and I can't read any of the button captions.
I installed gok via 'apt-get install gok'
