When a Greenfoot scenario is exported as a .jar file, the icon in the top-left corner of the window is automatically a green foot. Is there any way to change that, to choose an icon image (if I right-click on the .jar file shortcut (if I made one) then press on "Properties", in the Properties window there is a button "Change Icon", this button only changes the icon for the appearance of the .jar file shortcut on the desktop (and has to be .ico) in a JFrame there is a method for the picture in the top-left corner, and it doesn't have to be .ico)?
