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

Thanks. I've tightened a bunch of these queries in the past couple of weeks (exception is the result of us querying a device that is marked as not-present). Can you try upgrade to a recent version and see if hit it again?

[anaisbetts]

:+1: :cool:

[davkean]

How did you go, did you update to a later build? Have you seen this since?

[anaisbetts]

Haven't tried it yet, will give it a go soon
