The bug occurs in=20 Emacs 23.2 as well as a build from the current emacs-23 branch. But the=20 bug is gone in a build from the trunk. I wonder if the patch in=20 bug#6715 is what fixed it. At a glance, I don't see anything else=20 Cygwin-specific that might be relevant. When I get a chance, I'll see=20 if back-porting that patch to emacs-23 fixes the problem. Ken
