--- Comment #33 from Stefan Dösinger stefan@codeweavers.com 2012-01-19 23:17:23 CST --- I accidentally sent a hacky patch for this to wine-devel a while ago: http://www.winehq.org/pipermail/wine-devel/2011-June/090454.html. It had some issues at the time, that's why I never sent it to wine-patches. Then I lost it due to a harddisk crash. It is patch 3 in the .tar.bz2 archive.
The closed bug report is not a good place to discuss this further development, wine-devel is a better place for that.
