JIT Won't Work

Okay in Visual Studio 2003 I am having a problem getting the Just-In-Time (JIT) debugger to work with my C# application with forms.

It works with console applications; I tested it with the code:
Code:

Code:

---

int i=0;
i=1/i;

---

And the console application lets me break and do all that stuff that it should do with the JIT but my application with forms doesn't.

I've made sure that in my machine.config file has JIT enabled and the same in app.config but still no luck. Anyone have any ideas?
