title: Intellij IDEA 2016.2 not responding to mouse clicks on OSX
body: <p>I cannot work any more with Intellij Idea, under OSX. After performing an IDE upgrade, the IDE main window (and any dialogs) has stopped responding to mouse clicks. The menu still works.</p>
  
  <p>I have tried setting the log level to trace, with no success in getting any information of a possible exception when reacting to a mouse click.</p>
  
  <p>The system is generating some thread dumps (a lot more under 2016.2, I have now downgraded to 2016.1.4). Is there a way to get more information to diagnose this issue?</p>
