Intermittent "Excel has stopped working" crash/errors when using Report Generator ("Reports - Run") to run reports or forms, triggered by multi-threading

Troubleshooting


Problem

Inside the 'main' Controller client, user clicks "Reports - Run". User chooses a report (or form) and runs it as a report. This opens up in Excel, and starts to run. An error appears. Problem is intermittent - the report/form runs successfully most of the time. The crash/problem is rare.

Symptom
