- - - - JIT Debugging **************
        To enable just-in-time (JIT) debugging, the .config file for this
        application or computer (machine.config) must have the
        jitDebugging value set in the system.windows.forms section.
        The application must also be compiled with debugging
        enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
