All is good right now for logging as far as I have tested it - see below

 From your earlier message from 2020-03-23, 12:32 p.m

In the mean time, this sequence should work:

InitializeMagick(NULL);

DestroyMagick();

  [ Do some defaults configuration ]

InitializeMagick(NULL);

After cloning the latest version of GM and running configure, I checked 
to make sure ProvideDllMain was disabled when I built my current app.
Just now, I tried to run my app without the first two lines and all 
worked as expected.

So, yes, if ProvideDllMain is not disabled, I (probably) would have to 
jump through those extra hoops - my misunderstanding

Again, thank you for the mods and your help; I think I'll be good for a 
while - at least I hope so :-)

      Isn't this "a lot of work" due to the automatic DLL initialization
      that you are easily able to disable and is now disabled by
      default?
