hello, i am currently working on a pong game and i wish to input a JButton on a separate Gui running on a different thread to restart the program. The problem which is occurring is that when i press the restart button the key listener fails to respond therefore the 'rackets' do not move, while other processes such as the ball and point incrementation do. Therefore in conclusion, please may you tell me what the problem is, and the steps and the steps necessary for its fixing.
