Hi,
This was with an install of OCP 3.6.2, Myriad 3.6.2, totally uninstalled both beforehand, and then reinstalled. Diagnosis was remotely done by a PSquared tech whose name escapes me, but I've since reproduced it reliably on one of our production PCs. Auto Importer 3.6.2 has the same problem alongside Myriad 3.6.2.
