put into named field weirdness

Wow. Thank you.

That was completely counterintuitive, but, you are 100% correct.

Now, after opening my prefs stack, I have a line:

set the defaultStack to [NAME_OF_MY_MAIN_STACK]

..and now, inside of my readPrefsFile handler, I'm back to:

put lNewFilesList into field "FilesField"

..and the "Chunk: No such object" error is gone.

I don't think I ever would have figured that out. I mean, I thought
'this stack' would always refer to the stack whose script is running.

So, is there another way to refer to the stack that the currently
executing script belongs too? One that remains constant? Maybe
something like 'target owner'?
