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