[PySide] Problem with show/showFullScreen and Keys' events

[Chimera77]

Hi all,
I'm using PySide 1.1.0 and Qt 4.7.4 on a notebook with Vista OS.
I have encountered a strange behaviour with this simple qml code:

import QtQuick 1.1
Rectangle {
     width: 800; height: 480
     Keys.onPressed: {
         console.log("Captured:", event.text);
     }
}

If I use, in Python code, the command "show", I am able to capture
keys'events and I see log on console, but if I use the command
"showFullScreen" I don't log anything. Where is the mistake?

Thanks! Manuel
