IDEA 8.1.3 always listens on a socket trying to run an app in debug mode

I am trying to run my app in debug mode, when I click on the debug

icon, IDEA 8.1.3 starts in listener mode always. It starts to wait

for connections, it is as if I provided -Xdebug in the command

line option, how to avoid this? how to make IDEA run in

debug mode without listening for connections?

thanks
