************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for
this
application or machine (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
machine
rather than being handled by this dialog.
