Created an attachment (id=11308)

the backtrace when wine crashes, when one tries to close the help

This is the full text backtrace I mentioned earlier, when wine crashes,
if one tries to close the host-managed help windows.

I think there is a problem with windows management and parent/child
relationship, 
probably related to these messages when the help windows are created in the
first place:

fixme:urlmon:URLMonikerImpl_BindToObject use running object table
fixme:win:WIN_CreateWindowEx Parent is HWND_MESSAGE
fixme:shdocvw:BindStatusCallback_OnProgress status code 11
fixme:shdocvw:bind_to_object BindToObject failed: 80004005

It is also curious that, although the help windows are created,
and correct content is displayed, the application (R) didn't receive
the right reply and behaves as if the help launch was a failed. These are
probably all related - i.e. "crash on close" = 
"wrong parent/child relationship" = "wrong status to application launching
help"
