--- Comment #5 from Dan Kegel dank@kegel.com 2008-10-18 18:06:37 --- How did you install native comctl32?
Did you try using winetricks? It works around a known difficulty with overriding that.
cd $HOME mv .wine .wine.old wget http://kegel.com/wine/winetricks sh winetricks comctl32
If that makes it work, you probably don't need to do the regression test.
