Re: [ANNOUNCEMENT] TEST RELEASE: Cygwin 2.3.0-0.6

You were correct Corinna. It was indeed the administrators group that
was the owner. Windows security is perplexing to an old Unix-hand like
me. I guess something in the process of migrating and restoring my
home directory from another PC made the admin group the owner instead
of me. Luckily I have found this TAKEOWN utility which seems to fix
the issue.
