Steve,
What I mean is that you can
only use the soft input panel may it be letter recognizer or keyboard or transcriber, I think the app was designed that the text input/preview screen would be called up when the soft input panel is called up and the text input/preview screen would be called down when this is closed. And I think the Micro keyboard minimizes the soft input panel once you hit a button (of course you won't need the soft panel) and so when this happens the text input/preview panel in agile closes as well.
I have tried contacting the makers of the app twice but have not recieved a reply which is no surprise as this app is freeware. anyway here is the link to agile messenger it's pretty neat just wish I could use my micro keyboard with it and it would be the best im app for me.
