do i have any thing that can stop getting key dispatch Time out error. For
not clicking the button for the second time i disabled the button. I have a
server that sends the msgs to the quiz application. When the server is
disconnected and when i am clicking on the button its not getting disable
early when compared when the server is connected. Can you give me the
suggestion to handle it?
