Yes, you are correct. Sorry about that.

Actors that we add after the flash behave normally. We run the same software on many computers in our lab but the problem only occurs on a few computers and never on others (even when running continuously for several days).

During a long ( multiple hours ) automated test, where a surgical instrument is moved through the scene repeatedly ( Made from implicit function sources and also combined into an assembly) , there is an issue - and the best way for me to describe it is that the assemblies " come apart.  Each actor in the assembly is moved to a deferent place in the scene, as if perhaps they " exploded ". We have videoed this and there seems to be a screen flash before the happens.
