1.About inner class Once you have coded an inner class, compiled once, the "Test$Inner.class" was generated in the project file. And than you makes some change to it (even delete the inner class), the "Test$Inner.class" still exsists and would cause error when you export the scenario to a jar file or web page. Guess that's because of the Inner class was not deleted by "remove" method in the Greenfoot IDE. 2.About LoadanImage form path. It happens when the scenario is exported and the Image was not DIRECTLY in the image folder, for example: image/test/board.jpg Would that happens on your Greenfoot? If so would that be fixed? @dav @mik @Someone in Greenfoot Team
