why is Mate popup window is closing after every mate?

When i am trying to mate, every time mate popup window closes after every mate and again i need to press short cut key to start another mate which again closes after we provide one mate. ideally the mate window should close after 2 clicks. that is first one to confirm the mate and second one to exit the mate window. but in my case first click itself is providing the mate and coming out of mate command.

can some one help me correcting some setting related to mate.
