Just downloaded greenfoot and JDK and trying to teach myself using the tutorial but stuck on the first page!!! I am using the "wombats" scenario and when I try to place an object into the world by right clicking on the "wombat actor" I should get the option to add "new wombat" on the menu. However I only get the options, open editor, set image, remove and New subclass. (also in image in tutorial it look like there should be a grid in "the world" but I do not have this) Can anyone suggest what I am doing wrong.
