title: Missing "messages" window after compilation in IntelliJ
body: <p>I'm using IntelliJ IDEA 12. When I run "make project", "debug" or "run" task it does some compiling, shows little bubble that there are warnings, shows grayed-out tool window "message" and after few seconds it hides the nameplate of messages window.</p>
  
  <p>Why is compile log missing? What to do to fix this? I'd like to see (in IDE) what causes those warnings...</p>
  
  <p>PS: I'm not sure, but it might started doing this when I started using Scala (it's now a mixed Scala-Java project).</p>
