Screen Size Problems

Screen Size Problems

I've developed an application for a CE device. The screen size of the device is:
Horizontal: 240 pixels
Vertical: 320 pixels.
The problem that I am having is that the CE device Taskbar remains at the top of the screen and the keyboard remain at the bottom, this causes the navigation buttons at the bottom of the screen to be hidden.
Is there a way to disable the windows keyboard and the task bar when the zenon application is running? I still want to be able to use the keyboard and taskbar when the application is closed.
So far I have changed multiple screen settings without any success.
