I think it won't show up if we fix bug with accented URLs, because first help page is with accented char and that's why you have that msgbox.
No, regardless of the accented issue, the main body of htmlhelpW() is doing something wrong, htmlHelpW() at the moment does not return a handle to the parent application. Some parent application actually uses the handle.
