Apologies for the formatting error.

Thanks for the reminder, but it's not that. I defintiely logged
in. And amazingly, it's more than 20 years ago I was helped on this
list to understand this nuance, I think with regards to running
Oracle's sqlplus command line.

Speculating... it appears registry keys for the sync'ed portions of
the filesystem are usually subkeys under 
HKLM/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/SyncRootManager/
That suggests tie-in with Explorer... which suggests the Shell
extensions are not active somehow? I speak with complete lack of
authority of course.

One thing I could maybe do though, is profile the forked process
layout in Process Explorer, maybe look at which DLLs are in scope for
the relevant shell processes.
