@samhouts - I don't recall what version I was on. How best to check?

@samhouts Also, I've tried to create a small project which reproduces the issue. The new, simpler project does not reproduce the error. Further, I have refactored my code and the issue still presents, each time I execute the project.

Prior version may have been 4.0.0.425677. That's the default on my workstation when creating new projects.

Disregard. Recomplied with older versions, same issue.

Looks like this was a regression in 3.6. It appears to work in 3.5. Thanks!
