Actually the problem exists only if I use JGR. If I launch R from a terminal window then the text on-line help works.
It used to work with JGR too but with R version 2.9.0.
Now, JGR shows the new R version is running but the on-line help is no more available from JGR.
Perhaps JGR implementors will come up with some suggestion to fix this problem.  
Thank you,
Maura

You could switch to text-based help by editing RHOME/etc/Rprofile.site 
or your personal Rprofile, but you probably want to fix the bigger 
problem, which is that your system can't open the URLs that R is giving 
it.  Can you open any URL?  E.g. does 
browseURL("http://www.r-project.org")  open that web page?  If not, the 
problem is that your system doesn't know how to open a browser.
