Xcode stopping problem

I reinstalled Xcode because I was having a problem. Everything works well now except for 1 thing. When I run a project I press run and then stop to end it. But if the program crashes I can't stop it by pressing the stop button? When I run it again I get a message popping up saying it is still running and asks if I want to 'Stop Task'. I say yes and nothing happens? I started just selecting the button 'add'. The only way to fix this is to force quit Xcode.

Has anyone else had this problem or am I missing something?

 

Hi lloyddean, yes that is very familiar looking and I do that too. The problem is the next step. When you try to stop the task from running by pressing the Stop button. I get no response and it keeps running. I have to force quite the xcode to get it to stop the task. It's almost like it is stuck in an infinite loop that I can not exit?
