title: I can't see AVD manager window in android studio 0.4.0
body: <p>I am using windows 8,android studio 0.4.0 jdk 7_45 and jre7 installed. JAVA_HOME and JAVA variables are also set in Environment Path Variables.</p>
  
  <p>When I click on tools-> android->avd manager , it shows nothing (not even error anywhere) . Nothing at all happens.</p>
