Black screen in inner preferenceScreen
<p>My <code>PreferenceActivity</code> contains a nested <code>PreferenceScreen</code> in another <code>PreferenceScreen</code> and I'm applying a theme to my <code>PrefenceActivity</code> that changes the background color. However when I open the nested <code>PreferenceScreen</code> I get a black background and I cannot see the options.</p>

<p>This happens with android 2.1 , but it does not happen with android 1.6.
Any ideas on how this can be corrected?</p>
