The diagonal lines indicate that the class has not been compiled (either 
at all, or since the source was last changed). You can't create a new 
instance of a class until you have compiled it.

Either use the "compile" option offered when you right-click on a class, 
or use the compile button on the left of the BlueJ main window to 
compile everything which needs it.
