title: JavaFX background-image works in scenebuilder and win but not on osx
body: <p>I have a simple FXML which has a background-image defined for a tab-pane in an external css-file. </p>
  
  <p>The background-images is located in a image-directory which is placed in the same folder as in the .FXML</p>
  
  <p>The problem is that this background-image is being displayed in SceneBuilder (Win 7 and OSX Mountain Lion) but when running the application, only on Windows 7.</p>
  
  <p>I'm using Netbeans 7.2 and also tried updating to JDK 7.0_06 on OSX. I also made sure that my project is being build with 7.0_06.</p>
  
  <pre><code>#mainNavigation .tab-content-area,
  #mainNavigation .tab {
    -fx-background-color: #dddddd;
    -fx-background-image: url('./img/tabpaneBG.png');
  }
  </code></pre>
  
  <p>What else might I try?</p>
