So this would appear to be an Emacs bug or feature. I am using the Emacs 24.3.1 (i386-mingw-nt6.2.9200) of 2013-03-17 on MARVIN binary downloaded from Gnu site. Please try the 24.4-rc1 release candidate, this issue is supposed to be solved there, or at least work better. If the latest 24.4 version still doesn't solve the problem, please file a bug report ("M-x report-emacs-bug RET") with all the details. It would be best if you could show a short self-contained Lisp program and a small C client program (or an existing utility) that together demonstrate the problem. Thanks.
