The problem seems to be in the communication between Moray and POV-Ray 3.6. 
As you say, I remember that very early on you did try to solve the problem 
but could not find the glitch.
Maybe it would be valuable to make again a list of the specific problems 
happening. I wonder now if everybody who has met with some problem, have met 
with the same ones?

As mentioned in a thread above, my main problem is with the render of a 
material preview. Both Moray and POV-Ray freeze, with message "An unexpected 
error occurred while trying to make POV-Ray render the material. (code 3)".

This behaviour is... not consequent :-(
I have now also have the case where a (simple) material is rendered the 
first time, but next is not, POV-Ray telling me that "A render has completed 
but file output was turned off. No file was written. Press F1 for help on 
output file control.". After clicking OK, * something*  finishes. However, 
if I try to render the material again, Moray closes down abruptly and 
Windows asks me if I want to register a bug.

So far, what I have met with now....
