title: Eclipse menus disabled on OS X 10.9 Beta 6
body: <p>today I opened my eclipse as usual but I wasn't able to do anything. All menus except the preferences are grayed out, disabled.</p>
  
  <p>I'm on a Mac Mavericks Beta 6 &amp; Eclipse Kepler</p>
  
  <p>Do u have any hints for me? Restart of Eclipse or the complete mac didn't solve the problem</p>
