Ahh thank you, that might be something I can work with. Coworkers of mine are actually right in the middle of upgrading to version 7.4 which I expect to be finished any time soon!
Still pretty strange to me that the BackgroundWorker doesn't run and the PeriodicBackgroundWorkerBase does run in our current situation. If you can shed any light on this, that would be great!
Right now, to continue the feature, I'm implementing the periodic version. Since it's a singleton I've implemented the 'isRunning' solution so we actually only have it running once. And also enables some kind of auto-recovery option in case the process crashes.
