If the button start is pressed the variable "startPressed" is set true but the if clause in the "Game" class doesn't react to the new value. If i add System.out.println() or sleep then the if clause is recognizes the value and is giving me the output. I thought maybe there is a main problem in the programming structure or Java is to slow. Any ideas?ThanksLg Andrej
