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

Continue allows me to go an an operate as normal

How to repeat:
very intermittent had it 3 times now over 5 days

Thank you for the bug report. Could you provide the .mwb file to verify if it is repeatable at our side?. Thanks in advance.
