title: css menu hover "hangs" in chrome & safari
body: <p>Greetings -
  Struggeling with a three-level css menu.<br>
  Works fine in FireFox and Opera for mac, but in Chrome and Safari the third level "sticks" or "hangs" as a watermark after you move the cursor away. </p>
  
  <p>I have tried a few different things without luck.   </p>
  
  <p>Live demo here:  </p>

  <p>I have cut away everything else, so this is just the menu css &amp; html.<br>
  (PS. there are only three levels on archeology, hominins and environmental)</p>
