The link that you provided uses wxApp::FilterEvent() to catch a key press.

Maybe use something like the following in MyApp:

int FilterEvent(wxEvent& event) {
    if (event.GetEventType() == wxEVT_KEY_DOWN) {
        wxMessageBox(wxString::Format(wxT("%d"), ((wxKeyEvent &)event).GetKeyCode()), wxT("KeyCode"));
        return true;
    }
    return -1;
}

I just make a litle project, same in Ubuntu and windows xp
In xp run very well.
The same project, making from beggining, in Ubuntu there is not respond in key press.
So the problem is in OS or WXWidgets or in C::B?
