Website with JS doesn't work in IE9 until the Developer Tools is activated

problem ：

I'm developing a complex website that heavily leverages jQuery and a number of scripts. I am developing a complex website , It makes full use of jQuery And many scripts .On load of the site, none of my scripting is working (though I can confirm that other scripts are functioning fine). When loading the website , None of my scripts work （ Although I can confirm that other scripts are working properly ）.I wouldn't be posting such a lame question here on SE except for one thing: Except for one thing , I won't be here SE Publish such a lame question on ：

The instant I hit F12 to turn on developer tools so I can debug my issue, everything instantly works perfectly! I click F12 Open developer tools , So that I can debug my problem , Everything is perfect immediately ！

Worse, if I shut down the browser, start it up, turn on Dev Tools first and visit the site, everything works as expected. What's worse is , If I close my browser , To start it , Start by opening Dev Tools And visit the site , Everything works as expected .

So I can't even debug the darned problem because Dev Tools fixes it!
