Hi,
The bug in comctl32 that makes treeviews get messed up on collapsing nodes...
ROS: http://www.reactos.org/bugzilla/show_bug.cgi?id=2843 WINE: http://bugs.winehq.org/show_bug.cgi?id=10544
Could someone having wine sources / GIT, please create a patch and send it to the wine-patches mailing list.
Thanks, Timo
