title: Menu doesn't appear after linking to another page with phonegap
body: <p>I use phonegap, </p>
  
  <p>When linking to another page with simple href my menu stop working.</p>
  
  <p>In my Java class I override onKeyDown() and return false for menu button</p>
  
  <pre><code>@Override
  public boolean onKeyDown(int i,KeyEvent e){
      if (i==KeyEvent.KEYCODE_MENU){
          return false;
      }else{
          return true;
      }
  
  }
  </code></pre>
  
  <p>When I loadUrl from the java class I can open the menu (in about.html)</p>
  
  <pre><code>@Override
  public boolean onCreateOptionsMenu(Menu menu) {
      MenuInflater inflater = getMenuInflater();
      inflater.inflate(R.menu.main_menu, menu);
      return true;
  }
  
  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
      // Handle item selection
      switch (item.getItemId()) {
      case R.id.exit:
          this.finish();
          return true;
      case R.id.about:
          super.loadUrl("file:///android_asset/www/about.html");
          return true;
      default:
          return super.onOptionsItemSelected(item);
      }
  }
  </code></pre>
