Pudd makes the web work for you.

After installing Windows 7 recently, I noticed that I had no control over whether Visual Studio allows me to switch of client-side debugging.

The idea behind it is ok - you can step through code as it runs to check everything goes smoothly - but it really slows other tasks down.

Fortunately, you can trick Visual Studio to stop this - even if you do have IE8 running. It's actually IE8 that's the problem (if we're all agreed that it's a problem). IE8's "Disable script debugging" doesn't knock this debugging out... so it runs everytime, increasing the page load time from a fraction of a second to 10-20 seconds.
