I followed the steps described in http://docs.oracle.com/javafx/2/get_started/fxml_tutorial.htm, but the result differs from Figure 4-5 on that page, in that there's a black bar to the left of the actiontarget element (see screenshot.png in enclosed zip file).

I could reproduce the problem by changing the text property of the welcome-text element to text="", and the -fx-effect in the css to "dropshadow( gaussian , rgba(255,255,255,0.5) , 0,0,0,1 );" -- "innershadow" and "dropshadow( three-pass-box" did not have the same effect.
