************** 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.
