I am working on the stickman project. I am required to use the getMicLevel method in the Greenfoot class but whenever I try to use this method it shows me a redline underneath the method. Is it because I am using a Windows 7?
A red underline indicates a compilation error. If you click somewhere in the underlined text, you should see the error message in the status area at the bottom of the editor window, which might give an indication of what the problems is. (I don't understand why you think using Windows 7 is causing a problem?)
