I conjecture that this "Help" pushbutton opens the html user manual,
because when I press it, I see this on the console:

00be:err:winebrowser:launch_app could not find a suitable app to open
  L"file:///home/greg/.wine/dosdevices/z:/opt/lmi/data/user_manual.html"

Perhaps we should nevertheless remove it, though for a different
reason--namely, that what it does is not useful in context. The html
user mainly describes menuitems (and their corresponding toolbaritems),
which are not accessible while the tabbed dialog is displayed.
