Re: dispose(); not working
Only add the listener once. It will be called for each time it is added.

Re: dispose(); not working
please can you show me the line of code you use to only add a listener once?
public class game extends JFrame implements ActionListener{
isit like this?
Re: dispose(); not working
It is not possible to control the logic with a single line of code.
For example: If the addListener() method is in a loop it will be added many times.
Or if it is in another method that is called many times, it will be called each time.

What good is that? There needs to be code that can be tested.

Re: dispose(); not working
Find why the actionPerformed() method is called more than once?
Add a println() next to the line where the addActionListener() method is called to see how many times it is called. If it is called more than once, then you need to move the call to addActionListener() to where it is only called one time.

Re: dispose(); not working
Looks like the same listener is added 4 times to 4 different buttons. That wouldn't be a problem if only one button is pressed.
I'm done for tonight. Back tomorrow.

Re: dispose(); not working
I have been playing around with the game. I did what you said and added the system.out.println as you can see in the code below:

Re: dispose(); not working
To see what events are causing the actionPerformed() method to be called, add a println statement to print out the ActionEvent object that is passed to that method. A lot of info will be printed and somewhere in that printout you can see what component sent the event.

Re: dispose(); not working

Re: dispose(); not working
Did you look at what was printed out in the actionPerformed() method to see what component sent the ActionEvent?
I've lost my version of the source for this problem. I can't compile and execute it for testing.
