Guys, it's a well known issue between me and the POV-Team that we have
spent some time looking at, but haven't been able to resolve. At this
point, it's not clear whether it's a POV-Ray bug or a Moray bug. While
I tend to think it's a POV-Ray problem, neither the POV-Team nor I
could find the root of the problem (the code does not return from a
SetFocus() call to Windows). I will be devoting more time to it next
week to see if I can find a workaround or fix. 

Note that Moray does not crash. It hangs while trying to communicate
for about 5 seconds after which normals processing resumes for a short
while. Then it waits another 5 seconds, etc. This means you can leave
Moray with Alt-F4 or whatever means and save your work. You do need to
kill POV-Ray. The menu item Tools|Reset POV-Ray Comms was actually
meant to detach Moray from POV-Ray, but I think it doesn't work if the
Material Editor has been opened. My current developer version of Moray
can recover with this menu item.
