Weird Visual Studion 2008 behavior on windows 7 x64

Hi. I'm having this odd issue. I have Visual Studio 2008 Professional SP1 Installed on Windows 7 Ultimate x64. I noticed this, VS is not detecting any runtime exception thrown during the formLoad event, in C#. I haven't try this on VB. For example, this code:

object p = new Point(3, 4);
p = (Rectangle) p;

This doesn't do anything and the VS is not throwing any exception.

It is definitely throwing an exception, you'll see it in the Output window. However, it is getting caught and silently swallowed when you use the debugger. Very annoying. Not quite sure where this comes from, I noticed this starting somewhere with VS2008. This won't happen in production, try Ctrl+F5 for example. Debug + Exceptions, Thrown checkbox will catch it too.
