Okay, Ronald, you're suffering from the UID wrapping problem.  Cygwin UIDs
are currently 16 bit, so any number higher than 65535 will get wrapped
(and did).  You can change your UID to any unique number smaller than
65535 (56297 should do as well as any other).  I don't know that that's
the cause of your mc problem, but it's something to fix nonetheless.

If it turns out to fix your problem, it's a bug in 'mc', IMO.
