Android: Image buttons move when clicked for no reason

I have a very annoying problem with the android context menu: Randomly the pressed-state-color of a (pressed) entry in a context menu is wrong (darker as it should).

now after hours I can reproduce this behaviour with the following code:

public class MainActivity extends Activity {

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

public class MainActivity extends Activity { /** Called when the activity is first created.
