Something we can't pinpoint. There is a process not ending for eCabinets, so it can't open. Two options we have found work arounds for now. You can either after closing open Task Manager, then close the eCabinets process that is still running. The other option is before launching eCabinets, right click and choose Run as Administrator. When you close eCabinets it will close as expected. Still working on trying to get a repeatable computer to do it here in house so we can really dig in to what the issue is.
