unreported exception java.net.MalformedURLException; 
must be caught or declared to be thrown 
Desktop.browse(new URL  ( "http://www.google.co.uk/"));
                                       
C:\CW1 - Game\Game.java:174:

Are you putting that in a try-catch clause? If so, what does it look like?

No I don't, just simple check for action event which is build on if statement

Java Syntax (Toggle Plain Text) 
  1. else if(evt.getSource() == menuItemRules)
  2. 	{
  3. 		Desktop.browse(new URL( "http://www.google.co.uk/"));
  4. 	}

Anytime you mess with a URL you'll need to catch a malformedURLException and for the desktop thing,

Java Syntax (Toggle Plain Text) 
  1. else if(evt.getSource() == menuItemRules)
  2. 	{
  3.             try
  4.             {
  5. 		Desktop.browse(new URL( "http://www.google.co.uk/"));
  6.             }
  7.             catch(MalformedURLException mue)
  8.             {
  9.                //error message
  10.             }
  11.             catch(DesktopException de)
  12.             {
  13.                //error message
  14.             }
  15. 	}
