I'm creating a simple, old, black and white tennis game for practice. I've created an event handler for 9 keys - 2 for moving 2 paddles up, 2 for moving them down, 2 for left and 2 for right. I also have an Enter key that starts the ball moving. The problem is that when I press Enter, none of my other keys work, until the ball goes off the screen. Does anyone have any suggestions how to fix this

Here is the code:
private
void Start_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e){
//Down1
if(e.KeyCode == Keys.S){
if(paddle3.Top < 315){
int y = paddle3.Top+3;paddle3.Top = y;
}
}
//Up1 if(e.KeyCode == Keys.W){
if(paddle3.Top > 0){
int y = paddle3.Top-3;paddle3.Top = y;
}
}
//Left1 if(e.KeyCode == Keys.A){
if(paddle3.Left > 0){
int x = paddle3.Left-3;paddle3.Left = x;
}
}
//Right1 if(e.KeyCode == Keys.D){
if(paddle3.Left < 235){
int x = paddle3.Left+3;paddle3.Left = x;
}
}
//Down2 if(e.KeyCode == Keys.K){
if(paddle2.Top < 315){
int y = paddle2.Top+3;paddle2.Top = y;
}
}
//Up2 if(e.KeyCode == Keys.I){
if(paddle2.Top > 0){
int y = paddle2.Top-3;paddle2.Top = y;
}
}
//Left2 if(e.KeyCode == Keys.J){
if(paddle2.Left > 350){
int x = paddle2.Left-3;paddle2.Left = x;
}
}
//Right2 if(e.KeyCode == Keys.L){
if(paddle2.Left < 575){
int x = paddle2.Left+3;paddle2.Left = x;
}
}
if(e.KeyCode == Keys.Enter){
moveBall();
}
}

Thanks for all of the help from everyone, but I've already found the problem and now everything works perfectly.
What happened, was that moveBal() was a function that moved the ball by 1 to 5 pixels in each direction. This happened in a 'for' cycle that only ended when the ball went off the screen. Thus, the call kept reoccuring, and none of my other handlers would work. I fixed this by impleminting a timer, which moved the ball with each tick of 5 milliseconds, and changed by Enter handler to start the timer.

I see that you have implemented all that on single thread .
Try using multithreaded approach so as to keep your User interface responsive .
Thanx
