Thanks for the reminder, but it's not that. I definitely 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. I don't know how much that 
would help. -- Regards, Shaddy
