title: IntelliJ IDEA not responding to mouse clicks
body: <p>I have a problem with IntelliJ IDEA Community Edition 12.1.6. <br> Everything works fine, as long as I have only one project (one window) opened. When I open second/third etc. project, only the first one responds to mouse clicks. <br>Every other project reacts to keyboard input (Ctrl+TAB, Alt+arrows etc.), but not to mouse input. I'm able to modify code, use keystrokes, so the application is not frozen.<br>
  I tried to reinstall the app, no effect. The last update was a couple of weeks ago and the problem appeared today.<br>
  I'm using Ubuntu 10.04.</p>
  
  <p>Has anyone here encountered similar problem?
  <br>Oh, and is there some magical place, where log files are stored?</p>
