Visual Studio 2012 breaking on JavaScript exceptions when debugging in Internet Explorer 9

Question

I'm debugging a web site (not web project, unfortunately) in Visual Studio 2012 with Internet Explorer 9 and it seems to keep breaking on JavaScript exceptions with the standard Unhandled exception at line x, column y in script block dialog. This happens in a new tab titled script block [dynamic].

At this stage I'm really not concerned with the underlying exception, I just don't want Visual Studio to tell me about the exceptions at all.

I've changed every obvious setting I can think of. So:

Visual Studio Settings

Exception settings -> JavaScript Runtime Exceptions: both Thrown and User-unhandled are unchecked.

Tools -> Options -> Debugging -> Just-In-Time: Script is unchecked

Internet Explorer 9 Settings

Internet Options -> Advanced: Disable Script Debugging (Internet Explorer) and Disable Script Debugging (Other) are both unchecked.

This doesn't happen if I debug using Firefox or Chrome, but unfortunately I'm forced to use Internet Explorer 9.

How can I fix this problem? Are there any options I might be missing?

Try the Web Essentials extension for VS. I'm fairly sure it stopped when i installed this. alternatively you can try Debug=>Attach to=> then Select.... (but you might have to do this a lot...)
