Re: Missing CMFCRibbonBar::OnHelpHitTest()
It appears that it is really CMFCRibbonBar::OnToolHitTest() that is missing.
CBasePane::OnHelpHitTest() ends up calling CWnd::OnToolHitTest(), which is
virtual. Classes like CMFCToolBar override OnToolHitTest() to return the
button at the specified location. Because CMFCRibbonBar does not override
OnToolHitTest(), CWnd::OnToolHitTest() is called instead and it tries to
find the child window at the specified point. Since ribbon elements are not
actual windows, CWnd::OnToolHitTest() finds no child windows and returns -1.
As a result, CBasePane::OnHelpHitTest() simply returns the ID of the ribbon
window itself, which is useless here.
Is this a bug?

appear to exist?
If you don't know, this is the handler for the WM_HELPHITTEST. MFC sends
this message to handle ID_CONTEXT_HELP, which is when you click the help
arrow and then click on a window or button to view the help associated
with that command.
It appears this functionality is completely broken when you use the
