VM: Java HotSpot(TM) 64-Bit Server VM, 19.1-b02, Java(TM) SE Runtime Environment, 1.6.0_24-b07
OS: Linux

User Comments:
jkovalsky: I was debugging Anagram Game project. I made a GUI Snapshot, displayed listeners on some component, then setup component breakpoint on another component and then clicked into the white space below the GUI snapshot in Editor.
