I suppose it's possible that on Windows the whole "current drive"

Right, I meant ``the local equivalent of "~"''

Dunno again.  It's something that comes up for me with Gnus far, far
more often than with anything else I'm doing in Emacs... so solving it
in Emacs might be even more of an uphill battle than solving it in Gnus
is.

Great questions.  Dunno #3.  I just know it makes my life miserable :-)
