--- Comment #2 from Austin English austinenglish@gmail.com 2010-07-10 21:56:52 --- Still present. Easy test:
terminal 1: $ wine notepad # type some text
terminal 2 $ wineboot -e #end-session
notepad will prompt you to save the text if you use wineboot -s or wineboot -r (restart/shutdown), you are NOT prompted.
wine is still not warning apps though, so if you do: $ wine notepad # type asdf then shutdown/restart your system, you'll get no warning.
