xcode 4.1 instrument (let's say Leaks) noresponse

Ok, now I've fixed the bug! If I'm opening XCode, choose Profile and choose one instrument (let's say Leaks) the new Instrument window opens. Then I need to go back to XCode (while Instrument.app window is still open in background!) and have to use command + tab to choose out of xcode in front the Instrument.app again. Then the instrument app shows me the tracked data. Really weird problem, but now it works. ;-) 

意思是，起动后，先切换到xcode 界面，然后再去command +tag ,切换到 instrument就可以了。我这里这样可以解决，起动时无响应的问题
