Swing application crashes in while loop

Question

The following code is a fragment from a battleships game using Swing.
Once the user has placed all their ships on the board, this function is called. The problem is, it does not allow the user to guess the computers ships location. When a location on the comkputers grid is clicked nothing happens. Is the while loop looping too fast for the app to recognise that a button has been clicked?
private void startGame(){   
          //while somebody hasnt guessed all their opponents ships
          while (!(isGameOver())){
               //if users turn                             
              if(myTurn)
                    //set value of last button clicked to -1
                    NumberOfLastButtonClicked = -1;
                    //enable buttons for user
                   enableButtons(false, true);     
                   //add note on screen to indicate it is the user's turn
                   appendToStatus("Guess opponents fleet locations:");              
                    //this loops around until the variable has been assigned a value between
                    //0 and 99 i.e a button has been clicked
                   while (NumberOfLastButtonClicked==-1){
                    //disable buttons for user
                    disableButtons(false, true);
                    //set user turn to false
                    myTurn = false;
              //its computers turn
              else
                   //computer takes a guess
                   computerGuess();
                   //set user turn to true
                   myTurn=true;
             //execute code to finish game
             endGame();
    }

You immediately turn disable the users buttons after telling them it's their turn. I'm guessing that's not what you want to do.
The style of programming you are using here is polling. This is a problematic way to do things.
Instead of looping and looking to see what was selected, you should have the users input trigger the processing directly. Add a listener to the button that sets the my turn state and calls the a game() method.
