title: Hyperledger Composer - Not getting console.log messages
body: <p>For some reason, I've stopped getting console.log() messages to the dev javascript browser console. </p>
  
  <p>I'm running HyperLedger Composer locally on a Mac. </p>
  
  <p>My Current Environment - <code>
  ├── composer-cli@0.19.1
  ├── composer-playground@0.19.1
  ├── composer-rest-server@0.19.1
  ├── generator-hyperledger-composer@0.19.1
  ├── npm@5.6.0
  ├── wscat@2.1.1
  └── yo@2.0.2</code></p>
  
  <p>Otherwise I'm operating fine.  I reinstalled the fabric-tools directory, and restarted the playground. No change. </p>
  
  <p>Thanks in advance for your help. </p>
