--- Comment #13 from Vincent Povirk madewokherd@gmail.com 2009-11-27 11:07:21 --- It seems the desktop window no longer gets a close message because of commit 9dbdd708e3530ace523bd3dc047bee6d17b65871. I guess the desktop window could be special-cased, but since this is safer than the previous behavior, we should probably fix wineboot --end-session first.
