You can use vi. You just have to write back with w! Corinna > Secondly, cp takes a source file that I can read and copies it to a target > file that I subsequently can't read.

When you open a file, either it works or it doesn't. vim checks the permission bits to show the [readonly] text in the status line and marks it as readonly. That doesn't mean you can't write it if the Windows permissons allow it. > posix permissions, but I can cat it.

This is consistent with POSIX semantics which states that when copying a file the POSIX ACL isn't copied as well. Having file permissions set for "authenticated users" but not for the actual owner is Win32 semantics. There's no 1:1 translation.
