 Confirmed -- Reader DC works great. FWIW, PDF Architect 4 has the
 same behavior as Sumatra (opens the manual but not to the correct
 chapter).
 
With the latest snapshot it works fine here with SumatraPDF on Windows 7 
(both first opening and then updating the view/ changing the chapter 
from the builtin docs).
