 Hi,
 I´ve tested gretl2016b-git (2016/03/02, MS-Windows x86_64) on Windows 10 and 
 Adobe Acrobat Reader (15.010.20059) and it works fine.
 Only a detail... when I click in the first link of the help on (e.g.) 'genr' 
 then it correctly opens chapter 9 of User's Guide, but if this window remains 
 open, if I click on the link of the help on (e.g.) 'join' then don´t opens 
 the chapter 7. So one must close the pdf before clicking a new link.
 That's right? 
That depends on the particular PDF viewer. With Acrobat Reader, you're 
right. If we passed the "/n" switch to Reader that ought to open a new 
instance of the program in which the PDF is opened at the second 
destination, but I'm not sure that's what the user would want 
(multiple copies of Reader running).
Interestingly enough, evince works just as one might wish in this 
case: clicking a second link shifts the read position to the new 
destination.
