I am tinkering with ASP.NET MVC and jQuery and making my first baby steps in a whole new horrible world of web development. I found out that the JavaScript IntelliSense in Visual Studio 2008 is broken out of the box. The error is:

Warning    2    Error updating JScript IntelliSense: jquery-1.3.2.js:
   Object doesn't support this property or method @ 2173:1

The fix for Visual Studio 2008 SP1 by Microsoft can be found here:
