What are the Customization and Size features? The X seems to follow behind the window.

I forgot to mention (I posted the other comments) that I changed the touch(Class clss) method to just be getOneTouchedObject(clss) != null as all the code for it instead of having all the code there twice (not exactly the same code but does the same thing).

"...just take a look...by taking a look in the ButtonWorld-class" All I see is a purple ball, and when clicked it disappears and a new one appears somewhere else. I don't see any place that allows me to look at classes or documentation. The part I like about it is you made it that when the mouse is hovered over the button it gets a little faded, and there's text displayed in a tool tip. But the scenario in itself isn't very exciting. I just used the setToolTipText method in javax.swing.JComponent - even in Greenfoot. See this: http://www.greenfoot.org/scenarios/19241 But in that particular scenario I didn't use the method.

Does it sound like I'm complaining? (It doesn't "sound" and it probably does look like it.) You're saying that there is no change to be made to your code?(!) (I don't have any necessarily, but the code can still be changed.) I was dealing with the code because to open the .gfar file I clicked on it, which opened the scenario - with errors. So I just wanted to see if I can make there not be any errors (before I got to the .jar file), but it was too complicated to fix everything, especially if there is no purpose to do so which is my problem.

"If you decide not to trust it, you can download..." On the last upload you forgot to check the "Publish source" box (that specific detail doesn't save from time to time).
