                            • 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:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

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.
