Sure. I mentioned NT5 because NT4's security tab told me that it suspected
that a system running NT5 may have screwed things up. Of course, we don't
have NT5. My guess was that CYGWIN was to blame instead, and I wasn't
wrong, was I?

Ok.

This depends on how you define 'correctly'. I started with a directory
tree on a remote shared drive which I can read (and I think also write,
but this should be irrelevant here). I copy the tree to my local drive,
on which I have full control, using CYGWIN's cp command. The outcome is
that I cannot read any of the copied files or directories. This is
certainly not what I would have expected.

Using the security tab one is offered the opportunity to overwrite the
"non-standard" security information which can be used to fix the
situtation after the copy.

As I explained, it is not only the GUI interface. I cannot access the
files until I manually 'fix' the security information.

Thanks for the pointer. Even after reading this I don't see how it
explains what happens in this case.

The only convenient solution for now, is to revert to CYGWIN-b20 which
works as I would have expected.
