This was a good hint! (It is seemingly so obvious, but
somebody has to say it) Thank you a lot.
I found that two services have argumentGetter blocks
that open a file in read-only mode. You find these in
 FileContentsBrowser class>>serviceBrowseCode
 ChangeList class>>serviceBrowseChangeFile

The blocks are evaluated in SimpleServiceEntry>>
getArgumentsFrom:  and getArgumentsFrom:
is sent in 

To see that the argument getter blocks are evaluated,
when you call up the menu, you can put a  self halt. 
into the blocks.
For a quick test, I removed the statements from the
blocks and I was then able to rename and to delete
the files that I could not previously rename or delete.

What shall we do with the services and the argument getters?
Advice from the creators of the services concept is

on an windows machine

This is interesting, but dont ask why Linux is different. 

Thank you again, Ned, and have a nice day
