Created an attachment (id=11307)
 --> (http://bugs.winehq.org/attachment.cgi?id=11307)
screenshot after patch 11306

screenshot after 11306, showing that the help content navigation now works
correctly.

It also shows that there is something wrong with the windows management -
The help window should be inside and part of the MDI/EDI main windows rather
than
being managed by the host's windows managers (note different window both style
between the "R Graphics device 2" at the back generated by plot(), and the help
windows generated by ?str in the front.

Closing the host-managed help windows sometimes result in crash like this:

2 0x7dca845c WebBrowser_Release+0x5c(iface=<register EDI not in topmost
frame>
) [/usr/src/redhat/BUILD/wine-0.9.57/dlls/shdocvw/webbrowser.c:155] in shdocvw
(
0x00e1f198)
  3 0x7dca1475 OleObject_Release+0x15(iface=0x27d6f74)
[/usr/src/redhat/BUILD/wi
ne-0.9.57/dlls/shdocvw/oleobject.c:270] in shdocvw (0x00e1f1a8)
  4 0x7de3e949 ReleaseWebBrowser+0xa9(info=<register ESI not in topmost frame>) 
[/usr/src/redhat/BUILD/wine-0.9.57/dlls/hhctrl.ocx/webbrowser.c:661] in hhctrl
(
0x00e1f1d8)

I'll attach the full log.
