Hey,
As soon as the last hhctrl patch is committed (embedding in the correct window), HTML Help will be functional. That means that you can open up a chm help file with wine's help viewer, hh. It requires IE6 to be installed for the time being, until our shdocvw and mshtml are up to par. You'll also need a copy of native itss.dll (it has to be registered with wine):
$ regsvr32 itss.dll $ WINEDLLOVERRIDES=shdocvw,mshtml,urlmon,shlwapi,itss=n wine hh helpfile.chm
A few things need to be completed, but not much. Most noticeably the toolbar buttons need to be drawn and submitted to wine-patches. If you would like to help in that area, send me an email and I'll let you know how it needs to be done. The tabs are blank and need filling in. Attached is a screenshot of hh in action. If anyone has any comments or suggestions, let me know and I'll address those.
Thanks, James Hawkins
