Hi,
I have a JApplet window in that window I have added a JPanel. In that JPanel I had drawn a image. I added the keyListener to the JPanel. But the Key listener is not working


2. If i click the empty panel after i press "1" the key listener is working? why it happen?

Any one knows please tell me ?
