I create c++ console application in Xcode 4 and build it. App works normally, but when I try to debug, I can’t use any button in Product/Debug/

I tried with c++, iOS, object-c projects and I always see this window.
But if I use breakpoints I can stop running, but still can’t use steps.
Any suggestions??
In Xcode 4, you need to enable breakpoints, which enables Debugging, and then run your app. To do this, toggle the button beside the run (play) button (looks like a sideways bookmark), or use Command-Y, as seen in your screenshot.
