title: Emacs 23: Selection not highlighted
body: <p>I installed Ubuntu 10.04, and with it came Emacs 23. If I want to select text in Emacs, that works perfectly fine except the fact that the region is not highlighted.</p>
  
  <p>However, this only happens, if I try to make a region using the keyboard. If I select something with the mouse, it is highlighted as usual.</p>
  
  <p>Does anybody know, why the region is not highlighted and how to fix that?</p>
