title: Selenium difference on windows / linux
body: <p>I have a JUnit test that imports org.openqa.selenium.interactions.Actions.</p>
  
  <p>Specifically, I am using dragAndDrop, outlined <a href="http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/interactions/Actions.html#dragAndDrop%28org.openqa.selenium.WebElement,%20org.openqa.selenium.WebElement%29" rel="nofollow">here</a></p>
  
  <p>When I run the Junit test on my local machine (windows), it runs perfectly. However, when the same test is run on a Linux machine, the method does not work. Everything else in the test runs fine but the dragAndDrop method does not work. </p>
  
  <p>A co-worker said that it might have something to do "XVFB" but could not elaborate much.</p>
  
  <p>Any comments appreciated, thanks! </p>
