           Summary: Crash on close of hh when showing any real help file
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: shdocvw
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com


View a .chm file with hh.exe, then close it by clicking the go-away box.
Boom!  WINEDEBUG=warn+heap makes it happen slightly sooner, I'll attach the
log.
I can reproduce this with the .chm files from autohotkey and 7-zip,
probably any will do.  Log highlights:
