--- Comment #21 from Timo-Heikki Mäkelä imaxfun@gmail.com 2008-03-10 12:18:22 --- I think the hhctrl.ocx component would be correct for this just as in a Bug 11690, which is also about htmlhelp:HtmlHelpW. There Wine didn't crash initially, but, once that's been fixed here, the problem is very same. Bug 6801 would be an obvious second duplicate then. To me it seems you are the closest solving all these three bugs completely atm.
